Line Break to Comma
Join a list of lines into a single comma-separated line.
From a column to a comma list
Copy a column of values from a spreadsheet and you get one item per line, but often you need them as a single comma-separated string — for a form field, a query, a config value, or just to paste inline. This joins your lines together with commas in one step, turning a tall list into a compact line.
Paste the lines and they come back joined with commas.
The little choices that matter
Whether there is a space after each comma, whether items are wrapped in quotes, whether trailing empty lines are dropped — these small options decide whether the result drops cleanly into wherever it is going. A space after each comma reads better in text; no space is tidier for code. It is a focused tool for one common direction; if you also need to go the other way, splitting a comma list back onto lines, that conversion is available too.
Common questions
Can I add a space after each comma?
Yes — include a space for readability or leave it out for a compact string, whichever the destination needs.
Can it go the other way, comma back to lines?
Yes, splitting a comma-separated list back into one item per line is available too.
Is my text uploaded?
