Frequently asked questions

Does this handle CSV files with commas inside a field?

Yes. Standard CSV wraps a field containing a comma in quotes (like "Doe, John"), and this tool parses and re-exports that correctly, including fields with quotes inside them.

Can I create a new CSV from scratch instead of editing one?

Yes, choose "start with a blank grid" to get an empty 3x3 grid you can fill in, add rows and columns to, and export as a new CSV.

Is there a limit to how large a CSV I can edit?

No hard limit, but very large files (tens of thousands of rows) will feel slower, since every cell is rendered as an editable field in your browser.

Is my CSV data uploaded anywhere?

No. The file is read and edited entirely in your browser using JavaScript. Nothing is sent to a server.
