Split a CSV column into several.
Turn a single column holding 'red,blue,green' into separate columns. Enough columns are created for the widest row, so nothing is truncated.
Everything runs in your browser. Nothing is uploaded.

Common questions
How many columns will I get?
As many as the row with the most parts needs. Rows with fewer parts get empty cells rather than being truncated.
Can I keep the original column?
Yes, and it is kept by default so you can check the split before discarding the source.
Is my file uploaded anywhere?
No. The file is parsed and processed entirely in your browser using JavaScript. It never leaves your device, and nothing is stored on our servers.
