Turn newline text into a comma-separated list or split it back.
Paste clean values, choose a separator preset, and copy the result. Open advanced settings only when you need a custom separator or cleanup toggles.
Quick answer
This tool joins newline text into comma-separated, pipe-separated, tab-delimited, space-delimited, or custom output directly in the browser.
It also splits comma-separated and other delimited strings back into one value per line, which is useful before cleanup, dedupe, quoting, or export edits.
Input
Multiline text
Output
Joined string
Best for clean values
If you do not need quote characters or wrappers, this page is faster than the multiline formatter. Use it for delimiter-only changes like CSV cleanup, pipe-separated logs, or tab-delimited exports.

- Use Multiline when you need quotes and wrappers too.
- Use Quote / Unquote when only the quote character is changing.
- Use JSON when the text becomes structured payload data.
FAQ
How is this different from the multiline formatter?
This page only changes delimiters. It does not add quote characters or wrapper tokens like brackets or parentheses.
Can I split pipe-separated or tab-separated strings?
Yes. Use the matching preset or type a custom separator. Escape sequences like \t and \n are supported.
Will it trim extra spaces?
Yes. Keep the trim option enabled and the tool will normalize values before joining or splitting them.
