Frequently asked questions

What if my values contain commas?

Handled automatically. The writer wraps any value containing a comma, quote, or newline in quotes, so the CSV reads correctly in every standard parser.

Is the header preserved?

Yes. When 'First row is a header' is ticked the first row is kept exactly as-is at the top.

Can I switch to a different output delimiter?

Yes. Change the output delimiter to semicolon, pipe, or a custom character if you don't want commas.

Is there a size limit?

Up to 2 MB of input per job, comfortably tens of thousands of rows.
