Check a Shopify product CSV before import

See the problems before you import

This built-in example has a repeated size and a price containing a currency symbol.

• Line 3: duplicate variant — size S already appears for linen-shirt.
• Line 3: price format — review $39.00; the price field expects a number.
• Line 2: overwrite warning — an empty Vendor can clear an existing value during an update.

These are example findings, not a check of your file. Open your CSV below for your own report.

Check supplier catalogs repeatedly? Set up the same checks in n8n.

Check the next supplier file automatically

Use the n8n workflow to run the same validation in your catalog process, route files with blocking findings, and download line-level CSV issue reports.

1. Download the tested n8n workflow and import it.
2. Choose your API plan and add your own RapidAPI key in n8n.
3. Run the two tutorial examples, then connect your existing CSV text source.

The tutorial makes two API requests per run. It does not import products or connect to your Shopify store. CSV text is sent to the API when the workflow runs; this browser checker processes your file locally.
