Convert a list of lines into a comma-separated string.
A list into one line
Turning a column of items into a comma-separated string is a constant need for code arrays, SQL lists, and spreadsheets. This tool joins your lines and can quote each item for you.
Paste a list, and it returns a single comma-separated line. Enable quotes to wrap each value — handy for building a code array or an SQL IN list — and trim to clean stray spaces.
Simple and private
The conversion runs in your browser, so nothing you enter is uploaded.
