Free tools for difficult supplier files.

Convert a catalog. Compare a price list. Get a file you can inspect before making changes to your store.

Your files stay in your browser.

No account or subscription is needed. These tools process local files on your device and download the result back to you. Saved setups contain field and matching choices, not your catalog data.

Start with the included synthetic samples. The free limits are 5 MB per file, 5,000 rows per table, 120 columns and 250,000 cells. Large or unusually nested catalogs may need to be split first.

Preparing for WooCommerce?

Conversion and comparison are preparation steps. Check our import guides for mapping, parent relationships and controlled updates. For a file that needs a human review, see CSV repair.
