Shopify's product import fails per-row, not per-file - so a single bad price or a mismatched Option1 Name three thousand rows in can mean re-uploading and waiting through the whole import again just to find one cell. This checks a product CSV against Shopify's actual column rules before you upload it, and tells you exactly which row and column caused each problem.

When you'd use this

Before any bulk import or re-import - especially catalogs exported from another platform, since column names and formats (delimiter, price formatting, boolean values) rarely match Shopify's exactly on the first try.

It's also useful for catching the relational mistakes that a spreadsheet won't warn you about on its own: variant rows that don't share their parent's Handle, duplicate SKUs scattered across the file, or Option1/2/3 Name values that drift between rows that are supposed to belong to the same product.

Common errors

Errors (shown in red) mean the import will fail outright for that row - a missing required column, a price with a currency symbol in it, or an invalid barcode. Warnings mean the import will succeed but produce a wrong result, like a compare-at price that's lower than the actual price.

A semicolon-delimited file (common from European spreadsheet exports) is detected automatically - if your file still looks garbled, it's usually an encoding issue: this tool flags the character patterns that indicate a UTF-8 file was saved or re-opened as Latin-1 somewhere along the way.
