Remove duplicate rows

Find and remove duplicate rows in a CSV or Excel file, like the same email twice. Free, private, nothing uploaded.

How it works, privately

How it works, privately

  1. Choose your CSV or Excel file. You can also drop files on the page. They open in this browser tab; nothing is sent anywhere.
  2. Pick the columns that decide what counts as the same.
  3. Save the result to your device. Close the tab and nothing is left on any server, because nothing was ever sent.

Questions

Is it free?
Yes. Clean up CSV & tables is free to use, with no account, no sign-up and no daily limit.
Are my files uploaded?
No. Clean up CSV & tables runs inside your browser, on your own device. Your files are never sent to a server, so nobody else can see them.
Does it work on my phone?
Yes. It works in an up-to-date browser on phones, tablets and computers. Very big files are quicker on a computer.
Do I need to install anything?
No. Open the page and use it. You can also add Toolbox to your home screen like an app.
