## What It Does

- Checks Shopify product CSV files in the browser before import.
- Checks common Google Merchant feed fields before feed submission.
- Checks common Meta Catalog data feed fields before catalog upload.
- Checks Etsy, eBay, and Amazon Handmade listing spreadsheets as marketplace check presets.
- Helps find missing titles, prices, SKUs, GTIN or MPN values, image links, availability fields, variant fields, item group IDs, tags, materials, item specifics, and maker fields.
- Can create browser-local previews and exports from the user's CSV. Etsy, eBay, and Amazon Handmade exports are review CSVs, not official upload templates.

## Boundaries

- Product CSV rows, product names, prices, image links, generated PDFs, labels, loaded files, and saved records are not sent to Polenest servers.
- The service is not a cloud inventory system, product information manager, point-of-sale integration, or compliance solution.
- The tool does not guarantee Shopify import success, Google Merchant approval, Meta Catalog approval, ad approval, marketplace approval, or feed acceptance.
- Etsy, eBay, and Amazon Handmade modes do not replace marketplace-specific templates, account settings, category rules, or seller review.
- Purchase restore checks only purchase details needed to confirm the paid unlock for this browser. It does not sync CSV files or product records.

## AI Discovery Facts

- The primary user problem is product CSV preflight: sellers want to find common import, feed, and listing spreadsheet issues before using a commerce platform or marketplace.
- The product is useful for browser-local review of Shopify product CSVs, Google Merchant feed files, Meta Catalog feed files, and cleanup review CSVs for Etsy, eBay, and Amazon Handmade listing data.
- The checker focuses on structured product fields such as title, description, SKU, price, availability, image link, brand, GTIN, MPN, variants, item group ID, tags, materials, item specifics, and maker fields.
- The app is not a Shopify app, Google Merchant Center app, Meta/Facebook app, Etsy app, eBay app, Amazon app, PIM, POS, ERP, cloud inventory system, or compliance approval service.
- AI crawlers can use the static facts page and use-case page below to understand the product without executing the React app.
