About This Calculator
Many systems want a comma-separated string instead of a vertical list. This tool takes one item per line and joins them with whatever separator you choose.
Empty lines are dropped and items trimmed, so the output is clean and paste-ready. Everything runs locally in your browser.

Frequently Asked Questions
Can I go the other way — from comma-separated to a list?
Not in this tool. To split a comma list into lines, use the "sort lines" or a delimiter tool. This one joins a vertical list horizontally.
Why use the "comma + quotes" option?
It wraps each item in quotes, which is required when values contain their own commas for valid CSV output.
