Free tools / CSV import checker

A small check.
Before a big import.

Find common CSV problems before they reach your next app. Clear findings, useful context, and a file that stays on your device.

What does a completed check mean?

The supported checks finished within the tool’s limits. It does not validate required fields, product rules or overwrite behaviour in your destination app. Keep a backup and test a small import first.

What is kept?

Your selected file is used in browser memory. Clear it or close the page when finished. Reports contain finding locations and counts, not original cell values or filenames. Normal page requests still occur; file contents are never sent by the checker.
