Is this free to use?
Yes. It is completely free, with no account, no signup, and no usage limits.
Does it work on a phone?
Yes. The page runs in any modern mobile browser, on iPhone and Android alike, with no app to install.
Do I need to install anything?
No. The tool runs entirely in the browser, so there is nothing to download or install.
Will it quote items that already contain a comma?
No. Items are joined exactly as typed, so an item with an internal comma will be indistinguishable from two items in the output. If you are producing CSV from names or addresses, add the quotes before or after the conversion.
Can I use a semicolon or a pipe instead?
Not in this tool, the separator is a comma and a space. Convert to a comma list here, then use find and replace in your editor to swap the comma for the character you need.
Does it remove duplicates from my list?
No, every non-empty line becomes an item, repeats included. Run the list through Find Unique List Items first if you want each value to appear once.
Can I paste a column straight from Excel or Google Sheets?
Yes. A copied column pastes as one value per line, which is exactly the input format. Blank cells become blank lines and are dropped automatically.
Is there a trailing comma at the end?
No. The items are joined between each other, so the output starts and ends with real content and there is nothing to clean up afterwards.
Is my list uploaded?
No. The conversion runs in the browser, which matters when the column is a list of customer emails, order IDs, or employee names.
