CATALOGLATCH / SHOPIFY CSV PREFLIGHTCheck your next CSV.
Before it touches the store.
A local Shopify CSV checker for agencies. Compare imports, flag risky changes and blank overwrites, and export client reports.
BUILT FOR CATALOG WORK
A calmer checkpoint before import.
For Shopify agencies and catalog specialists. Review the exceptions before making changes to a client’s catalog, and keep a record of the decision.
PrelaunchFind the exceptions
Inspect structural blockers, new handles, reused SKUs, and variant changes with source line numbers that point back to your CSV.
Keep a client record
Export findings and changes, or save a standalone report for a reviewable client handoff.
Keep files on your device
The checker reads CSVs locally. Your catalog stays on your device, with no store access or catalog uploads. Product image links are never fetched.
From spreadsheet to a reviewable decision.
- Load your files. Choose a UTF-8 Shopify product CSV and, for comparison checks, a fresh store export.
- Review the findings. Investigate blockers and changes using the original source lines.
- Share the handoff. Download findings or save a standalone client report before you import.
VERSION 1 / AGENCY EDITION
One focused tool. Across your client projects.
The checker supports standard Shopify product CSVs. The trial allows 100 data rows per file; the downloadable edition supports up to 25,000 rows per file, with a 20 MB maximum.
CatalogLatch reviews files; it does not edit or import your store. A clean report is a review aid, not a guarantee that every business decision is correct.
