Hi Product Hunt!
What CSV Preflight does: drop in your CSV, pick where it’s going (Amazon, Shopify, Etsy, eBay, HubSpot or Mailchimp), and it checks the structure, data quality and that platform’s rules, then fixes common issues for you.
🔒 Everything runs in your browser. Your file isn’t uploaded to my servers.
✅ Free for files up to 1,000 rows, no signup.
➡️ Walmart, TikTok Shop, WooCommerce and BigCommerce are coming next.
Why I built it: after 20 years in IT, I left this year to build my own tools. My first one came from frustration: KDP kept rejecting my book files with errors I couldn’t make sense of, so I built a checker to catch problems before upload.
CSV imports have the same problem. You upload a product feed or contact list, and the platform rejects it, or worse, accepts it and quietly drops rows, breaks dates or mangles special characters. Every platform has its own rules, and the error messages rarely tell you what’s actually wrong.
I’d love your feedback:
What’s the most painful CSV import error you’ve run into? I want to make sure it catches it.
Which platform should I add next?
If you try it on a real file, did it miss anything or flag something wrongly?
Thanks for checking it out. I’ll be here all day answering questions!
