Workflow
Built for pre-import checks.
Read the catalog, parse the CSV, and show what needs review. Another tool can run the import after the CSV looks safe.
Review the import decision
See whether to stop, review first, or continue with the current CSV.
Fix priority rows
Jump between issue cards and CSV rows, then export the issue list for teammates.
Checks
Designed around common CSV accidents.
Blank overwritesFind empty values that may replace existing product data.
Identifier mismatchesCatch SKU, Handle, and barcode rows that point to the wrong product.
Spreadsheet damageSpot scientific notation and barcode formatting issues before import.
Price risksFlag invalid, zero, negative, or malformed price values.
Variant driftDetect option and variation values that do not match current Shopify data.
Publication changesNotice CSV rows that may publish products unexpectedly.

Safety boundary
Read-only by design.
RowProof does not import CSVs, edit products, delete products, or auto-fix catalog data. It helps you decide what to do before another tool changes the store.
