Catch Shopify CSV import failures before you upload

Free in-browser checker for Shopify product CSVs. Your file never leaves your browser — no login, no API key, no store access. Row-level findings for missing handles, duplicate handles, header drift, encoding and price bugs. Optional $19 one-shot fixed CSV.
Honestly love that everything runs locally in the browser, makes it feel way safer to drop a raw CSV in without thinking twice. The row-level callouts for stuff like duplicate handles and encoding bugs are exactly what a hands-on Shopify team needs.

Thank you, Aleyna! The local-first constraint was actually the founding decision — a product CSV is essentially your whole catalog, so I didn't want anyone to have to trust a stranger's server with it. If you're curious, you can open devtools and watch the network tab: the file never leaves the browser.
Duplicate handles are the sneakiest failure in my experience — Shopify treats a repeated handle as an update, so one stray duplicate row can silently overwrite an existing product mid-import. That failure mode alone is why I started building this.
If your team ever hits an import failure the checker doesn't catch yet (encoding edge cases, variant quirks, etc.), I'd genuinely love to hear about it — the rule set grows from real broken files.
The fact that everything runs in the browser without an upload is such a thoughtful call. Makes it actually usable for stores nervous about sharing CSVs, and the row-level findings are exactly what you'd want when triaging a messy export.
