About CSV SafeCheck

CSV SafeCheck checks a single Shopify product CSV file for import problems before you upload it to Shopify, entirely in the browser. It reads UTF-8 CSVs up to 15 MB, flags the exact affected rows and columns, applies only conservative fixes, and produces a downloadable validation report. There is no signup, no upload endpoint, and no remote processing, the page's own security policy blocks outbound connections so the file never leaves your machine. The single-file checker is free and available indefinitely. A paid Local Batch Audit Pack adds the ability to check up to 25 files in one session, and a separate Agency Batch License extends that to internal use across up to 10 client projects, both delivered as one-time purchases through Lemon Squeezy.

The free plan in practice

What you can actually do on CSV SafeCheck's free plan (One file at a time, up to 15 MB and 100,000 rows per file), where it stops, and when it's worth paying.

What you can do free

Unlimited single-file Shopify CSV checks
Up to 15 MB and 100,000 rows per file
Exact affected row and column reporting
Conservative automatic fixes
Local JSON validation report

Where it stops

One file at a time only
Batch processing of multiple files requires the paid pack
Checks a documented subset, does not guarantee Shopify import acceptance

When to upgrade to a paid plan

Stay on the free plan while you're comfortably under the free plan's limit (One file at a time, up to 15 MB and 100,000 rows per file). It's worth moving to a paid plan once you consistently bump into that ceiling, need to remove branding, or want features the free tier holds back. Paid plans start at ZAR55 one-time for batch processing.
