Free Shopify Product CSV Checker

Drop your Shopify product CSV export and instantly spot the errors that break imports — empty handles, missing titles, missing or zero prices, duplicate SKUs, imageless products and more.

Your file never leaves your browser — 100% private. Nothing is uploaded.

Drag & drop your products.csv here

…or pick a file. It is parsed right here in your browser.

How it works

  1. 1

    Drop your CSV

    Export your products from Shopify (Products → Export → CSV) and drop the file here, or load the sample.

  2. 2

    We check it in your browser

    The file is parsed locally with JavaScript. Nothing is uploaded — it never touches a server, so it is completely private and free.

  3. 3

    See issues + the fix

    Get a dashboard of import-breaking issues, plus exactly how Lasso would fix each one without the spreadsheet.

Your file never leaves your browser

This checker is 100% client-side. Your CSV is read with your browsers built-in FileReader and analysed in JavaScript on your own machine — there is no upload, no server, no database, and no cost. Close the tab and the data is gone. We never see your products.

Stop fighting CSVs. Edit your store in plain English.

Lasso is a Shopify bulk editor you talk to. Change prices, tags, SEO, titles and more across your whole catalog from chat — with a visual diff before every apply and one-click undo after. Free to install.
