NONUO · PRODUCT PILOT

Find the small errors
before your next import.

Check a CSV for duplicates, uneven rows and missing values. Your file is processed in this browser.

Check a file

Choose a UTF-8 CSV · up to 2 MB / 10,000 rows

Comma-separated files with a header row. Source files are never modified. No account or upload required.

Check summary

Columns that must have a value

Reuse these checks

Save your required-column choices, then load them after choosing your next CSV. Columns are matched by name, even if their order changes. All standard CSV checks still run.

Load saved checks

Saved files contain selected column names only, without data rows. Files stay in your browser.

Detected issues
Row	Column	Issue	Explanation

Clear results. No silent fixes.

See what changed

Logical row numbers include the header. A quoted line break stays inside its record.

Keep control

This pilot flags issues and exports a separate report. It does not rewrite or upload your original data.

Know the limits

Email checks look at format only. Formula prefixes can be valid values. Review findings before changing data.
