Convert lists to comma-separated values
Spreadsheets, databases and APIs often need values in a single comma-separated line. This tool converts a column of items into that format instantly, and can also reverse the process.
The quote option wraps every item in double quotes, ready to paste into an SQL IN (...) clause or a CSV file.
Modes
- Add Commas: A, B, C from one item per line
- Remove Commas: splits a comma-separated string into lines
- Add Quotes: produces "A","B","C" for SQL and CSV
💡 Tip: Paste a spreadsheet column straight into the box, then copy the result into your query.
