RowProof is a read-only preflight checker for Shopify product CSV imports. It compares your CSV with current product data and highlights rows that may need review before another tool changes your catalog. Use it before native CSV import, Matrixify jobs, supplier updates, or bulk edits. It can flag invalid prices, damaged barcodes, missing matches, identifier mismatches, option drift, blank overwrites, and publication changes. The app does not import, edit, delete, or auto-fix products.

• Run read-only checks before importing product CSVs
• Spot risky prices, barcodes, identifiers, options, and blanks
• Review issue rows, CSV previews, and export fix lists
