About the Remove Empty CSV Columns

Spreadsheet exports often carry a tail of empty columns created by a stray click. They make every downstream import wider than it needs to be.

Only columns where every cell is empty are removed - a column with a single value survives.

Questions people ask

Is your data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your data never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
