Frequently Asked Questions

Why do Google Sheets CSV exports have formatting issues?

Google Sheets exports often include merged-header artifacts, mixed decimal formats, and empty trailing rows or columns. Rightrow automatically strips empty padding, normalizes headers, and standardizes numbers and dates.

Can I clean data directly in Google Sheets without exporting?

Yes. In addition to this web tool, Rightrow provides a free Google Sheets Add-on that cleans and standardizes your spreadsheet data non-destructively directly within your Google Sheet.

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.
