What is a Comma Separator?

A comma separator tool helps you convert between different list formats. It can add commas to a line-separated list (creating CSV format), remove commas from CSV data (creating a line-separated list), or convert between different separators entirely.

This tool is essential for data preparation, whether you're formatting data for spreadsheets, preparing SQL queries, creating arrays for programming, or converting between different data formats.

All processing happens locally in your browser for privacy and speed. Your data is never sent to any server.

Features

Add Commas Mode

Convert line-by-line lists into comma-separated values. Perfect for creating CSV data from vertical lists.

Remove Commas Mode

Convert comma-separated data back into a line-by-line list. Ideal for working with CSV data in other formats.

Convert Separators

Change between any separator types: commas, newlines, tabs, semicolons, pipes, or custom delimiters.

Quote Items

Optionally wrap each item in quotes (single, double, or backticks). Perfect for SQL queries or programming arrays.
