About Comma Separator
The Comma Separator tool makes it easy to reformat lists into your desired delimiter format. Paste a list of items — whether separated by new lines, commas, or mixed delimiters — and convert it to comma-separated, semicolon-separated, space-separated, or any custom format you need.
This tool is especially useful for formatting data for CSV files, SQL IN clauses, programming arrays, or spreadsheet imports. The option to wrap items in quotes is handy for creating proper CSV output, while the duplicate removal feature helps clean up messy data lists.
Everything runs in your browser with no server processing, so your data stays private. Whether you're a developer preparing data for code, a marketer cleaning up keyword lists, or an analyst formatting data for a spreadsheet, this tool saves you time on tedious manual formatting.
Frequently Asked Questions
Q What formats can I convert my list to?
You can convert your list to comma-separated (,), semicolon-separated (;), newline-separated, space-separated, tab-separated, pipe-separated (|), or any custom delimiter you specify. Simply select the separator type from the dropdown or choose "Custom" to enter your own delimiter string.
Q When should I use the "Wrap in quotes" option?
The "Wrap in quotes" option wraps each item in double quotation marks, which is useful when creating CSV-formatted data. This is especially important when your items contain commas, spaces, or special characters that could break CSV parsing. For example: "New York", "Los Angeles", "San Francisco".
Q Can this tool handle mixed input formats?
Yes! The tool automatically splits your input by common delimiters including newlines, commas, semicolons, and tabs. This means you can paste messy data with inconsistent formatting and the tool will extract individual items correctly. Just paste your data and click Process.
