+I will provide a JSON array with product data. Process the array by combining all products from validData and invalidData arrays into a single array, excluding any fields starting with “__”, such as “__index” or “__errors”. Process each product according to the reference guidelines below. If a field is not included in the data, do not include it in your response (e.g. do not include its key or any value) unless the specific field guidelines below say otherwise. If a product appears to be from an empty or entirely invalid line, do not include it in your response.
+
+Your response should be a JSON object with the following structure:
+{
+  "correctedData": [], // Array of corrected products
+  "changes": [], // Array of strings describing each change made
+  "warnings": [] // Array of strings with warnings or suggestions for manual review (see below for details)
+}
+
+IMPORTANT: For all fields that use IDs (categories, supplier, company, line, subline, ship_restrictions, tax_cat, artist, themes, etc.), you MUST return the ID values, not the display names. The system will handle converting IDs to display names.
+
+Using the provided guidelines, focus on:
+1. Correcting typos and any incorrect spelling or grammar
+2. Standardizing product names
+3. Correcting and enhancing descriptions by adding details, keywords, and SEO-friendly language
+4. Fixing any obvious errors or inconsistencies between similar products in measurements, prices, or quantities
+5. Adding correct categories, themes, and colors
+
+Use only the provided data and your own knowledge to make changes. Do not make assumptions or make up information that you're not sure about. If you're unable to make a change you're confident about, leave the field as is. All data passed in should be validated, corrected, and returned. All values returned should be strings, not numbers. Do not leave out any fields that were present in the original data.
+
+Possible reasons for including a warning in the warnings array:
+- If you're unable to make a change you're confident about but you believe one needs to be made
+- If there are inconsistencies in the data that could be valid but need to be reviewed
+- If not enough information is provided to make a change that you believe is needed
+- If you infer a value for a required field based on context
+
+

+
+Fields: eta
+Changes: Minimal, you can correct formatting, obvious errors or inconsistencies
+Required: Return if present in the original data. Do not return if not present.
+Instructions: If present, return a full month name, day is optional, no year ever (e.g. “January” or “March 3”). This value is not required if not provided.
+
+Fields: name
+Changes: Allowed to conform to guidelines, to fix typos or formatting
+Required: You must always return a value for this field, even if it's not provided in the original data. If no value is provided, return the most reasonable value possible based on the naming guidelines and the other information you have.

If a value is unusual or unreasonable, even wildly so, change it to match similar products or to be more reasonable. When correcting unreasonable weights or dimensions, prioritize comparisons to products from the same company and product line first, then broader category matches or common knowledge if necessary.Do not return 0 or null for any of these fields.
+
+Fields: coo
+Changes: Formatting only
+Required: Return if present in the original data. Do not return if not present.
+Instructions: If present, convert all country names and abbreviations to the official ISO 3166-1 alpha-2 two-character country code. Convert any value with more than two characters to two characters only (e.g. "United States" or "USA" should both return "US").

+
+Fields: size_cat
+Changes: Allowed to correct obvious errors or inconsistencies or to add missing values
+Required: Return if present in the original data or if not present and applicable. Do not return if not applicable (e.g. if no size categories apply based on what you know about the product).
+Instructions: If present or if applicable, return one valid numerical size category ID from the Available Size Categories array below. Give preference to the value provided, but correct it if another value is more accurate. If the product name contains a match for one of the size categories (such as 12x12, 6x6, 2oz, etc) you MUST return that size category with the results. A value is not required if none of the size categories apply.
+
+Fields: themes
+Changes: Allowed to correct obvious errors or inconsistencies or to add missing values
+Required: Return if present in the original data or if not present and applicable. Do not return any value if not applicable (e.g. if no themes apply based on what you know about the product).
+Instructions: If present, confirm that each provided theme matches what you understand to be a theme of the product. Remove any themes that do not match and add any themes that are missing. Most products will have zero or one theme. Return a comma-separated list of numerical theme IDs from the Available Themes array below. If you choose a sub-theme, you do not need to include its parent theme in the list.
+
+Fields: colors
+Changes: Allowed to correct obvious errors or inconsistencies or to add missing values
+Required: Return if present in the original data or if not present and applicable. Do not return any value if not applicable (e.g. if no colors apply based on what you know about the product).

A value is not required if none of the colors apply. Most products will have zero colors.
+
+Fields: categories
+Changes: Allowed to correct obvious errors or inconsistencies or to add missing values
+Required: You must always return at least one value for this field, even if it's not provided in the original data. If no value is provided, return the most appropriate category or categories based on the other information you have.
+Instructions: Always return a comma-separated list of one or more valid numerical category IDs from the Available Categories array below. Give preference to the values provided, particularly if the other information isn't enough to determine a category, but correct them or add new categories if another value is more accurate. Do not return categories in the Deals or Black Friday categories, and strip these from the list if present. If you choose a subcategory at any level, you do not need to include its parent categories in the list. You must return at least one category and you can return multiple categories if applicable. All categories have equal value so their order is not important. Always try to return the most specific categories possible (e.g. one in the third level of the category hierarchy is better than one in the second level).
+
+----------PRODUCT NAMING GUIDELINES----------
+If there's only one of this type of product in a line: [Line Name] [Product Name] - [Company]
+Example: "Cosmos Infinity Chipboard - Stamperia"
+Example: "Serene Petals 6x6 Paper Pad - Prima"
+
+Multiple similar products in a line: [Differentiator] [Product Type] - [Line Name] - [Company]
+Example: "Ice & Shells Stencil - Arctic Antarctic - Stamperia"
+Example: "Astronomy Paper - Cosmos Infinity - Stamperia"
+
+Standalone products: [Product Name] - [Company]
+Example: "Hedwig Puffy Stickers - Paper House Productions"
+Example: "Heart Tree Dies - Lawn Fawn"
+
+Color-based products: [Color] [Product Name] - [Company]
+Example: "Green Valley Enamel Dots - Altenew"
+Example: "Magenta Aqua Pigment - Brutus Monroe"
+
+Complex products: [Differentiator] [Line] [Product Type] - [Company]
+Example: "Size 6 Round Black Velvet Watercolor Brush - Silver Brush Limited" (Size 6 Round is the differentiator, Black Velvet is the line, Watercolor Brush is the product type)
+
+These should not be included in the name, unless there are multiple products that are otherwise identical:
+- Product size
+- Product weight
+- Number of pages
+- How many are in the package
+
+Naming Conventions:
+- Paper sizes: Use "12x12", "8x8", "6x6" (no spaces or units of measure)
+- Company names must match backend exactly
+- Always capitalize every word in the name, including short articles like "The" and "An"
+- Use "Idea-ology" (not "idea-ology" or "Ideaology")
+- All stamps are "Stamp Set" (not "Clear Stamps" or "Rubber Stamps")
+- All dies are "Dies" or "Die" (not "Die Set")
+- Brands with their own naming conventions should be respected, such as "Doodle Cuts" for dies from Doodlebug
+
+Special Brand Rules - Ranger: 
+Format: [Product Name] - [Designer Line] - Ranger
+Possible Designers: Dylusions, Dina Wakley MEdia, Simon Hurley create., Wendy Vecchi
+Example: "Stacked Stencil - Dina Wakley MEdia - Ranger"
+
+Special Brand Rules - Tim Holtz products from Ranger:
+Format: [Color] [Product Name/Type] - Tim Holtz Distress - Ranger
+Example: "Mermaid Lagoon Tim Holtz Distress Oxide Ink Pad - Ranger"
+
+Special Brand Rules - Tim Holtz products from Sizzix or Stampers Anonymous:
+Format: [Product Name] [Product Type] by Tim Holtz - [Company]
+Example: "Leaf Fragments Thinlits Dies by Tim Holtz - Sizzix"
+
+Special Brand Rules - Tim Holtz products from Advantus/Idea-ology:
+Format: [Product Name] - Tim Holtz Idea-ology
+Example: "Tiny Vials - Tim Holtz Idea-ology"
+
+Special Brand Rules - Dies from Sizzix:
+Include die type plus "Dies" or "Die"
+Examples:
+"Art Nouveau 3-D Textured Impressions Embossing Folder - Sizzix"
+"Pocket Pals Thinlits Dies - Sizzix"
+"Butterfly Wishes Framelits Dies & Stamps - Sizzix"
+
+Important Notes
+- Ensure that product names are consistent across all products of the same type
+- Use the minimum amount of information needed to uniquely identify the product
+- Put detailed specifications in the product description, not its name
+
+Edge Cases
+- If the product is missing a company name, infer one from the other products included in the data
+- If the product is missing a clear differentiator and needs one to be unique, infer and add one from the other data provided (e.g. the description, existing size categories, etc.)
+
+Incorrect example: MVP Rugby - Collection Pack - Photoplay
+Notes: there should be no dash between the line and the product
+
+Incorrect Example: A2 Easel Cards - Black - Photoplay
+Notes: the differentiating factor should come first: “Black A2 Easel Cards - Photoplay”. Size is ok to include here because this is the name printed on the package.
+
+Incorrect Example: 6” - Scriber Needle Modeling Tool
+Notes: this product only comes in one size, so 6” isn’t needed. The company name should also be included.
+
+Incorrect Example: Slick - White - Tulip Dimensional Fabric Paint 4oz
+Notes: color should be first, then type, then product, then company, so “White Slick Dimensional Fabric Paint - Tulip”. It appears there’s only one size available so no need to differentiate in the name.
+
+Incorrect Example: Silhouette Adhesive Cork Sheets 5”X7” 8/Pkg
+Notes: should be “Adhesive Cork Sheets - Silhouette”
+
+Incorrect Example: Galaxy - Opaque - American Crafts Color Pour Resin Dyes
+Notes: “Galaxy Opaque Dye Set - Color Pour Resin - American Crafts”
+
+Incorrect Example: Slate - Lion Brand Truboo Yarn
+Notes: [Differentiator] [Line] [Product Type] - [Company] : “Slate Truboo Yarn - Lion Brand”
+
+Incorrect Example: Rose Quartz Dylusions Shimmer Paint
+Notes: “Rose Quartz Shimmer Paint - Dylusions - Ranger”
+
+
+----------PRODUCT DESCRIPTION GUIDELINES----------
+Product descriptions are an extremely important part of the listing and are the most important part of your response. Care should be taken to ensure they are correct, helpful, and SEO-friendly.
+
+If a description is provided in the data, use it as a starting point. Correct any spelling errors, typos, poor grammar, or awkward phrasing. If necessary and you have the information, add more details, describe how the customer could use it, etc. Use complete sentences and keep SEO in mind.
+
+If no description is provided, make one up using the product name, the information you have, and the other provided guidelines. At minimum, a description should be one complete sentence that starts with a capital letter and ends with a period. Unless the product is extremely complex, 2-4 sentences is usually sufficient if you have enough information.
+
+Important Notes:
+- Every description should state exactly what's included in the product (e.g. "Includes one 12x12 sheet of patterned cardstock." or "Includes one 6x12 sheet with 27 unique stickers." or "Includes 55 pieces." or "Package includes machine, power cord, 12 sheets of cardstock, 3 dies, and project instructions.")
+- Do not use the word "our" in the description (this usually shows up when we copy a description from the manufacturer). Instead use "these" or "[Company name] [product]" or similar. (e.g. don't use "Our journals are hand-made in the USA", instead use "These journals are hand made..." or "Archer & Olive journals are handmade...")
+- Don't include statements that add no value like “this is perfect for all your paper crafts”. If the product helps to solve a unique problem or has a unique feature, by all means describe it, but if it’s just a normal sheet of paper or pack of stickers, you don’t have to pretend like it’s the best thing ever. At the same time, ensure that you add enough copy to ensure good SEO.
+- State as many facts as you can about the product, considering the viewpoint of the customer and what they would want to know when looking at it. They probably want to know dimensions, what products it’s compatible with, how thick the paper is, how many sheets are included, whether the sheets are double-sided or not, which items are in the kit, etc. Say as much as you possibly can with the information that you have.
+- !!DO NOT make up information if you aren't sure about it. A minimal correct description is better than a long incorrect one!!
+
+Avoid/remove:
+- The word "Imported"
+- Any warnings about Prop 65, choking hazards, etc
+- The manufacturer's name if it's included as the very first thing in the description
+- Any statement similar to "comes in a variety of colors, each sold separately"

+![GitHub](https://img.shields.io/github/license/UgnisSoftware/react-spreadsheet-import) [![npm](https://img.shields.io/npm/v/react-spreadsheet-import)](https://www.npmjs.com/package/react-spreadsheet-import)
+  
+</div>
+<br />
+
+A component used for importing XLS / XLSX / CSV documents built with [**Chakra UI**](https://chakra-ui.com). Import flow combines:
+
+- 📥 Uploader
+- ⚙️ Parser
+- 📊 File preview
+- 🧪 UI for column mapping
+- ✏ UI for validating and editing data
+
+✨ [**Demo**](https://ugnissoftware.github.io/react-spreadsheet-import/iframe.html?id=react-spreadsheet-import--basic&args=&viewMode=story) ✨
+<br />
+
+## Features
+
+- Custom styles - edit Chakra UI theme to match your project's styles 🎨
+- Custom validation rules - make sure valid data is being imported, easily spot and correct errors
+- Hooks - alter raw data after upload or make adjustments on data changes
+- Auto-mapping columns - automatically map most likely value to your template values, e.g. `name` -> `firstName`
+  <br />
+

+
+## Figma
+
+We provide full figma designs. You can copy the designs
+[here](https://www.figma.com/community/file/1080776795891439629)
+
+## Getting started
+
+```sh
+npm i react-spreadsheet-import
+```
+
+Using the component: (it's up to you when the flow is open and what you do on submit with the imported data)
+
+```tsx
+import { ReactSpreadsheetImport } from "react-spreadsheet-import";
+
+<ReactSpreadsheetImport isOpen={isOpen} onClose={onClose} onSubmit={onSubmit} fields={fields} />
+```
+
+## Required Props
+
+```tsx
+  // Determines if modal is visible.
+  isOpen: Boolean
+  // Called when flow is closed without reaching submit.
+  onClose: () => void
+  // Called after user completes the flow. Provides data array, where data keys matches your field keys. 
+  onSubmit: (data, file) => void | Promise<any>
+```
+
+### Fields
+
+Fields describe what data you are trying to collect.
+
+```tsx
+const fields = [
+  {
+    // Visible in table header and when matching columns.
+    label: "Name",
+    // This is the key used for this field when we call onSubmit.
+    key: "name",
+    // Allows for better automatic column matching. Optional.
+    alternateMatches: ["first name", "first"],
+    // Used when editing and validating information.
+    fieldType: {
+      // There are 3 types - "input" / "checkbox" / "select".
+      type: "input",
+    },
+    // Used in the first step to provide an example of what data is expected in this field. Optional.
+    example: "Stephanie",
+    // Can have multiple validations that are visible in Validation Step table.
+    validations: [
+      {
+        // Can be "required" / "unique" / "regex"
+        rule: "required",
+        errorMessage: "Name is required",
+        // There can be "info" / "warning" / "error" levels. Optional. Default "error".
+        level: "error",
+      },
+    ],
+  },
+] as const
+```
+
+## Optional Props
+
+### Hooks
+
+You can transform and validate data with custom hooks. There are hooks after each step:
+
+- **uploadStepHook** - runs only once after uploading the file.
+- **selectHeaderStepHook** - runs only once after selecting the header row in spreadsheet.
+- **matchColumnsStepHook** - runs only once after column matching. Operations on data that are expensive should be done here.
+
+The last step - validation step has 2 unique hooks that run only in that step with different performance tradeoffs:
+
+- **tableHook** - runs at the start and on any change. Runs on all rows. Very expensive, but can change rows that depend on other rows.
+- **rowHook** - runs at the start and on any row change. Runs only on the rows changed. Fastest, most validations and transformations should be done here.
+
+Example:
+
+```tsx
+<ReactSpreadsheetImport
+  rowHook={(data, addError) => {
+    // Validation
+    if (data.name === "John") {
+      addError("name", { message: "No Johns allowed", level: "info" })
+    }
+    // Transformation
+    return { ...data, name: "Not John" }
+    // Sorry John
+  }}
+/>
+```
+
+### Initial state
+
+In rare case when you need to skip the beginning of the flow, you can start the flow from any of the steps.
+
+- **initialStepState** - initial state of component that will be rendered on load. 
+
+```tsx
+  initialStepState?: StepState
+  
+  type StepState =
+    | {
+        type: StepType.upload
+      }
+    | {
+        type: StepType.selectSheet
+        workbook: XLSX.WorkBook
+      }
+    | {
+        type: StepType.selectHeader
+        data: RawData[]
+      }
+    | {
+        type: StepType.matchColumns
+        data: RawData[]
+        headerValues: RawData
+      }
+    | {
+        type: StepType.validateData
+        data: any[]
+      }
+
+  type RawData = Array<string | undefined>
+
+  // XLSX.workbook type is native to SheetJS and can be viewed here: https://github.com/SheetJS/sheetjs/blob/83ddb4c1203f6bac052d8c1608b32fead02ea32f/types/index.d.ts#L269
+```
+
+Example:
+
+```tsx
+import { ReactSpreadsheetImport, StepType } from "react-spreadsheet-import";
+
+<ReactSpreadsheetImport
+  initialStepState={{
+    type: StepType.matchColumns,
+    data: [
+      ["Josh", "2"],
+      ["Charlie", "3"],
+      ["Lena", "50"],
+    ],
+    headerValues: ["name", "age"],
+  }}
+/>
+```
+
+### Dates and time
+
+Excel stores dates and times as numbers - offsets from an epoch. When reading xlsx files SheetJS provides date formatting helpers.
+**Default date import format** is `yyyy-mm-dd`. Date parsing with SheetJS sometimes yields unexpected results, therefore thorough date validations are recommended.
+
+- **dateFormat** - sets SheetJS `dateNF` option. Can be used to format dates when importing sheet data.
+- **parseRaw** - sets SheetJS `raw` option. If `true`, date formatting will be applied to XLSX date fields only. Default is `true`
+
+Common date-time formats can be viewed [here](https://docs.sheetjs.com/docs/csf/features/dates/#date-and-time-number-formats).
+
+### Other optional props
+
+```tsx
+  // Allows submitting with errors. Default: true
+  allowInvalidSubmit?: boolean
+  // Translations for each text. See customisation bellow
+  translations?: object
+  // Theme configuration passed to underlying Chakra-UI. See customisation bellow
+  customTheme?: object
+  // Specifies maximum number of rows for a single import
+  maxRecords?: number
+  // Maximum upload filesize (in bytes)
+  maxFileSize?: number
+  // Automatically map imported headers to specified fields if possible. Default: true
+  autoMapHeaders?: boolean
+  // When field type is "select", automatically match values if possible. Default: false
+  autoMapSelectValues?: boolean
+  // Headers matching accuracy: 1 for strict and up for more flexible matching. Default: 2
+  autoMapDistance?: number
+  // Enable navigation in stepper component and show back button. Default: false
+  isNavigationEnabled?: boolean
+```
+
+## Customisation
+
+### Customising styles (colors, fonts)
+
+You can see default theme we use [here](https://github.com/UgnisSoftware/react-spreadsheet-import/blob/master/src/theme.ts). Your override should match this object's structure.
+
+There are 3 ways you can style the component:
+
+1.) Change theme colors globally
+
+```jsx
+    <ReactSpreadsheetImport
+        {...mockRsiValues}
+        isOpen={isOpen}
+        onClose={onClose}
+        onSubmit={setData}
+        customTheme={{
+          colors: {
+            background: 'white',
+            ...
+            rsi: {
+              // your brand colors should go here
+              50: '...'
+              ...
+              500: 'teal',
+              ...
+              900: "...",

+
+Underneath we use Chakra-UI, you can send in a custom theme for us to apply. Read more about themes [here](https://chakra-ui.com/docs/styled-system/theming/theme)
+
+### Changing text (translations)
+
+You can change any text in the flow:
+
+```tsx
+<ReactSpreadsheetImport
+  translations={{
+    uploadStep: {
+      title: "Upload Employees",
+    },
+  }}
+/>
+```
+
+You can see all the translation keys [here](https://github.com/UgnisSoftware/react-spreadsheet-import/blob/master/src/translationsRSIProps.ts)
