About the CSV Column Selector

Columns can be named or given by 1-based position, which covers files with unhelpful or duplicated headers.

The output order follows the order you list them in, so this doubles as a reordering tool.

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.
