Check your product CSV for problems.
Choose a product export (Shopify, WooCommerce, a spreadsheet — any CSV). In seconds you'll see where listings contradict themselves, repeat, or carry invalid identifiers. Your file never leaves your device: the analysis runs in your browser.

What it checks
- Barcodes (GTIN/UPC/EAN) that fail the check-digit rule, or are used by two different products
- Duplicate SKUs and duplicate titles
- Empty or placeholder descriptions (“TBD”, “n/a”, “lorem ipsum”), missing or zero prices
- A title that says “500 g” or “12 pack” while the size/weight or pack-size column says something else
- Weights that do not fit the dimensions (a likely typo or unit mix-up), zero weights or dimensions, and one identical “default” weight on a large share of products — the kind of data error that leads to shipping under-charges
- Mixed weight units, inconsistent brand spelling, many listings without a brand, image or category
What this does not do: it looks only inside your file. It can show that two fields contradict each other, not which one is right, and it cannot compare against a manufacturer or product database. Results are candidates to check, not confirmed errors. Columns are recognised by common names (title, sku, gtin/upc/ean, description, brand, price, weight, length/width/height or dimensions, size, pack size, image, category); checks that need a missing column are skipped.
What happens next?
Catalog Audit is an early experiment. A human-reviewed audit service is being explored but is not available, and this site cannot take requests or orders. After a run you can tell us anonymously that you would want one (a single count; nothing about you or your file is sent).
