Free Comma Separator Tool
The Comma Separator turns a column of values into a clean, quoted, comma-separated list — perfect for SQL IN clauses, JavaScript arrays, or any place a parser expects items separated by commas.
How to Use
Paste one value per line, choose a quote style and separator, and copy the result. Blank lines and duplicate spaces are handled automatically.
- One value per line in, comma-separated out
- Single quotes, double quotes, or no quotes
- Choose comma, space, or newline separator
- Trim and optionally remove duplicates
- Runs entirely in your browser
