Know what your catalog will import.
Turn a supplier file into a WooCommerce-ready structure. See parent products, variations, prices, and row-level problems before you touch your store.
A safer first import starts with the small details.
For now, Catalog Mender supports one clear supplier template. It reports what it cannot safely carry through.
Keep every SKU intact
Leading zeroes stay. Duplicate or conflicting identifiers stop the repair before an import can go wrong.
Connect the variations
Sizes become child rows under the right parent, with the original prices and attribute values.
Show what needs attention
Unverified image links are left out and listed by source row. No missing value is invented.
Check the headers before you upload.
Catalog Mender currently accepts a UTF-8 CSV up to 10 MB with size-only variations. Download the sample to see the exact shape. We stop instead of guessing a missing identifier or price.
Download the sample CSV ↗| Parent SKU | Required product identifier; repeated across its size variations. |
|---|---|
| Product Name | Required. The same name for rows sharing a parent SKU. |
| Variant SKU | Required for each size variation; blank for a simple product. |
| Size | Required with Variant SKU; blank for a simple product. |
| Price | Required decimal amount without a currency symbol. |
| Image URL | Optional. Reported, then omitted until links can be checked safely. |
Know what you’re buying before you pay.
The free check lists blocking rows, unmapped columns, and a two-row sample. If your file fits this narrow template, one payment unlocks the complete repaired CSV for that exact file. You import it yourself into the built-in WooCommerce importer.
Extra supplier columns and unverified image URLs are not carried through. This is not a store migration or an existing-product update tool.
One complete CSV after a successful file check. No subscription. Sales tax, if applicable, is shown by Polar at checkout.
Available after a successful free file check.
Check your CSV first ↗Before you import
Will this change my WooCommerce store?
No. Catalog Mender gives you a CSV to review and import yourself. Test a small batch in a staging store first.
Can I upload a Shopify, Square, or Wix export?
Not directly. The first release needs the exact header template above and supports only a single Size attribute. Use the sample CSV to compare your file.
Are product images included?
No. We report source rows containing image links but omit the links from the output until their availability and safety can be checked.
Do you keep my catalog?
The API processes the upload for the request and does not keep the source or generated CSV. Your browser may temporarily store the selected file during checkout, and you can remove it by clearing site data.
Make the import easier to inspect.
One supplier CSV template. No store connection or hidden changes. Keep a backup and test the import before publishing.
