Schema comparison
See which required fields, allowed values, formats, and other product rules changed between two requirement versions.
Features
Turn changing product requirements into a focused review queue.
See what changed, which SKUs are affected, and why—without working through raw schema files or editing marketplace listings.
Per-SKU impact
Identify the exact products affected by a new rule, including the field and current value behind each finding.
Clear baseline
Separate new impacts from issues that already existed, products resolved by the change, and unaffected products.
Traceable evidence
Review the previous rule, the new rule, severity, current catalogue value, and a practical next step in one place.
Guided file import
Bring in CSV, XLSX, or JSON catalogues with a preview, suggested field matching, file checks, and reusable mappings.
Review-ready exports
Share findings as CSV or formatted XLSX files, with safeguards against spreadsheet formula injection.
