Frequently Asked Questions

How do I know if my CSV has an encoding error?

Encoding errors usually appear as replacement characters (like ), broken accents (e.g. é instead of é), or garbled punctuation. Rightrow detects whether your file is UTF-8, Latin-1, or Windows-1252 and re-encodes it cleanly into standard UTF-8.

Will repairing encoding alter my underlying data?

No. Repairing encoding only fixes character byte mappings. Your cell numbers, date values, and column structure remain unchanged.

Is this tool free to use?

Yes. You can test all diagnostic features and explore the cleaning pipeline using our 1-click interactive sample dataset with no sign-up or credit card required. To upload your own files and download sanitized exports, you can create a free Starter account in seconds (up to 250 rows per file, 5 cleaning runs per month).

What can I do without creating an account?

Without an account, you can launch the live interactive demo to inspect full data quality reports, view column profiling, review detected anomalies, and configure cleaning rules. Uploading your own files and exporting cleaned datasets requires a free account to ensure secure session handling.

Is my data private and secure?

Yes. Your data is strictly confidential. Files are processed securely in temporary session memory and purged immediately after processing. We never store your CSV records, never share your data, and never use your information to train AI models.
