How to convert a list to comma-separated values

  1. Paste your list into the input box — one item per line.
  2. Choose a delimiter from the toolbar: comma, semicolon, pipe, tab, space, or custom.
  3. Set quote style if needed — single quotes, double quotes, or none.
  4. Copy the output and paste it wherever you need it.

Common use cases

SQL IN clauses

Select double quotes and comma + space delimiter to produce a list ready for a SQL WHERE IN clause:

WHERE name IN ("apple", "banana", "cherry")

Spreadsheet formulas

Comma-separated lists paste directly into Excel or Google Sheets cells separated across columns when using the paste-special split option. Semicolons work for European locale spreadsheets.

Code arrays

Generate array contents for any language. Add double quotes and a comma + space delimiter, then wrap in brackets: ["apple", "banana", "cherry"].

Email and form fields

Many email platforms and form tools accept comma-separated lists for multiple recipients or tag values. Use the comma + space delimiter for clean, readable output.

Which delimiter should you use?

, (comma + space)SQL, readable CSV, most general-purpose use
, (comma only)Compact CSV, data imports without extra spaces
; (semicolon)European locale CSV, Excel in non-English regions
| (pipe)Log files, systems where commas appear in values
TabTSV files, Excel paste, clipboard-separated data
SpaceCommand-line arguments, bash arrays
CustomAny system with a unique separator requirement

Frequently Asked Questions

What is a comma-separated list?

A comma-separated list (also called CSV — comma-separated values) is a sequence of items joined by commas, typically on a single line: apple, banana, cherry. It is the most common format for importing lists into spreadsheets, databases, and code.

How do I convert a list to CSV?

Paste your list (one item per line) into the input box, select the comma delimiter, and copy the output. The tool joins all lines with a comma and optionally trims whitespace and removes empty lines.

Can I add quotes around each item?

Yes. Select single or double quotes from the options to wrap each item — for example: "apple", "banana", "cherry". This is required for SQL IN clauses and some CSV formats.

What delimiters are supported?

Comma, comma + space (", "), semicolon, pipe (|), space, tab, newline, and a custom delimiter you can define yourself.

How do I convert a list to a SQL IN clause?

Select double quotes (or single quotes depending on your SQL dialect), choose the comma + space delimiter, copy the output, and wrap it in parentheses: SELECT * FROM table WHERE name IN ("apple", "banana", "cherry").
