Turn one item per line into comma-separated text with trimming, blank-line cleanup, quoted output, and copy-ready formatting.
Frequently asked questions
Does this Newline to Comma tool upload my text?
No. The conversion happens in your browser, so the list does not need to be sent to a server for this tool to work.
Does it handle Windows and Unix line endings?
Yes. Windows CRLF and Unix LF line endings are normalized before the lines are joined.
What happens to blank lines?
Drop blanks is on by default, so empty lines are skipped. Turn it off if you want blank lines to become empty comma entries.
Does it trim spaces?
Yes. Trim lines is on by default, so spaces and tabs at the start or end of each line are removed before joining.
What does Avoid double commas do?
It removes commas already sitting at the end of input lines before adding the final separators, which helps prevent results like apple,, banana.
How do quoted items work?
Quoted items wraps every item in double quotes. Double quotes inside an item are escaped by doubling them.
Is this a full CSV converter?
No. It is focused on joining one item per line into a comma-separated result. More complex CSV, arrays, or SQL shapes would belong in separate tools.
Can I convert comma to newline here?
No. Comma to Newline is planned as its own focused tool, so this page stays centered on newline to comma conversion.
