Frequently asked questions

How do I convert an Excel column to comma-separated values?

Copy the Excel column, paste it here (each cell becomes one line), then click Convert. You get a single comma-separated line ready to paste anywhere.

Will extra blank lines break the output?

No. Empty lines are skipped automatically so you never get double commas in the result.

Is there a limit to how many lines I can convert?

No hard limit. The tool handles thousands of lines right in your browser.
