1. SheetJS js-xlsx

   1 69 36,231 2.4 JavaScript

   📗 SheetJS Spreadsheet Data Toolkit -- New home https://git.sheetjs.com/SheetJS/sheetjs

   

   Project mention: How to Convert Supplier CSVs to Shopify/Amazon/WooCommerce Without Uploading to a Server | dev.to | 2026-06-01

   The decision to process everything in the browser wasn't just about cost savings (zero server bills). It's a privacy feature: supplier inventory data, wholesale prices, and margin calculations never leave the user's machine. Technically, the app uses Papa Parse for CSV and SheetJS for XLSX, both loaded dynamically from CDN. The parsed rows are stored in a simple JavaScript array — no WebAssembly, no worker pool, just plain array operations that complete in under 50ms for typical supplier files.
