Shopify Products CSV Validator

Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.

No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.

You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.

Shopify exports one row per variant. A t-shirt with 3 sizes will have 3 rows with the same Handle.

Required columns are Handle, Title, Vendor, and Variant Price.

First transactions are free to preview. Full conversions use credits based on transaction count.

Save your CSV file as UTF-8 encoding and replace curly quotes with straight quotes. Open the file in a text editor and search/replace smart quotes if created in Excel.

Image URLs must start with http:// or https:// and link directly to the image. Images must be 5000 x 5000 px or smaller. Check that the URL is publicly accessible.

Your CSV file cannot exceed 15 MB. If larger, split it into multiple files under 15 MB each and upload separately.

This error occurs when a product has two variants with identical option values. Each variant must have unique option combinations to import successfully.

Column header names are case-sensitive and must match Shopify's template exactly. Check that headers like 'Title', 'Handle', and 'Variant SKU' are spelled correctly.

If tracking inventory with the Variant Inventory Tracker, you must provide a quantity. Leave the tracker field blank to skip inventory tracking.

Create one product in Shopify manually, export it as CSV, then use it as a formatting template. This shows correct headers and required field structure.
