Catalog CSV Check
The problem
Missing listing details, repeated IDs, and malformed prices or links can slip into a product catalog before it is published.
What this tool does
Review a one-product-per-row CSV in your browser. Map columns, inspect source-row findings and suggested fixes, then download an issue report.
Try the example
Choose “Load sample file” to see typical catalog issues, or use your own UTF-8 CSV. The original file is not changed.
The tool interface and findings are currently in English. Column names can be in any language when you map them manually.
Your CSV and issue report are processed in this browser; the tool does not upload their contents. The site separately uses Cloudflare Web Analytics for visit metrics. Page-level analytics is separate from file processing and does not include CSV cell contents.
Limits
This is a general preflight check, not a Shopify, Etsy, Amazon, or other platform validator. It checks currency-code format, not current validity or platform acceptance, and it cannot guarantee that an import will succeed.
