Comma Separator Tool
Turn a list of lines into a comma-separated list, or split a comma-separated list back into lines.
Between lines and commas
Data likes to travel as either one item per line or a single comma-separated string, and you constantly need to switch between the two — a column copied from a spreadsheet that a form wants comma-separated, or a comma list you want to see one item per line. This converts either way in a click, saving the tedious manual reformatting.
Paste your list and choose whether to join it with commas or split it onto lines.
The little formatting choices
Small options make the result fit where it is going: a space after each comma for readability, or none for a compact string; wrapping each item in quotes when the destination is code or a query; trimming stray spaces so items line up cleanly. Getting these right means the converted list drops straight into a spreadsheet, a form or a snippet of code without further fiddling.
Questions & answers
Can it convert both directions?
Yes — join lines into a comma-separated list, or split a comma list back into one item per line.
Can I add a space or quotes after each comma?
Yes, so the output suits whether it is going into readable text, a form, or code.
Is my text uploaded?
No. The conversion happens in your browser.
