Project mention: How to Convert Supplier CSVs to Shopify/Amazon/WooCommerce Without Uploading to a Server | dev.to | 2026-06-01
eBay: 30+ fields (item specifics, variations, shipping) Each schema is a JSON file defining field names, data types, and validation rules. The mapper walks source → target assignments and applies type coercion (string → number, date formatting, etc.) before export. The entire app stays under 200 KB gzipped by avoiding heavy UI libraries. It's built with Preact + htm (no JSX build step) and styled with Tailwind CSS v4. Export & Practical Considerations Export uses the standard Blob + download API. No server round-trip — just an ephemeral click with URL.createObjectURL(). The free tier handles 50 rows, enough to validate the mapping before committing. Column mapping profiles can be saved and reused, which is useful when the same supplier sends weekly inventory files with identical headers. Try It If you deal with supplier files regularly, you might find this useful. SKUMart handles all of this out of the box — just drop a file and export.
