How do I convert a comma-separated list to one item per line?
Paste the list into the converter above. Each comma is replaced with a line break automatically, turning horizontal text into a vertical list you can copy or download.
Will it break numbers like 1,000?
Enable "Ignore commas in numbers" and thousand separators are preserved while all other commas become newlines.
Is my text uploaded to a server?
No. The conversion runs entirely in your browser with JavaScript, so your text never leaves your device.
Can I convert back from newline to comma?
Yes, use our Newline to Comma Converter to join lines back into a single comma-separated line.
