Frequently asked questions

Before you use this tool

Is the CSV Duplicate Analyzer free to use?

Yes. You can use this tool in the browser without creating an account or installing software.

Does ClearCopies upload the data I paste?

No. This utility processes the pasted text in your current browser tab. Avoid pasting secrets, access tokens or unredacted exports into any online tool.

Can this tool delete or change my cloud-drive files?

No. This page does not connect to your cloud account and cannot rename, move or delete files. It produces an estimate, analysis or checklist for you to review.

What should I do after using the CSV Duplicate Analyzer?

Verify candidates in OneDrive before deleting anything. CSV parsing is intentionally simple; quoted commas and unusual exports should be normalized first.
