Scenario
Shopify CSV imports often fail because of small spreadsheet problems that are hard to see by hand. A missing Handle, an invalid column name, a duplicated SKU, a broken variant row, or an image URL Shopify cannot fetch can stop the import even when the file looks normal in Excel.
This tool page is for merchants who already tried to upload a product CSV and need to understand what went wrong before trying again. Upload the failed catalog workbook, or convert the CSV to XLSX first, then check the rows, columns, and product structures that may cause Shopify import errors. The goal is not to rebuild your catalog from scratch. It is to make the file easier to debug, correct, and re-upload.
The report should help you separate blocking issues from cleanup warnings. For example, a missing required field may need to be fixed before import, while a weak title or inconsistent image order can be reviewed after the file structure is stable. That makes the next upload more deliberate instead of another guessing round.
