Column to Comma Separated List

Use this free online tool to convert column-formatted text (with each item on a new line) into a clean, comma-separated list. Whether you're cleaning up data for Excel, preparing inputs for code, or organizing information for CSV files, our tool makes the job fast and simple.

What is a Column to Comma Separated List Converter?

This tool takes a list of values—typically pasted from a spreadsheet, database export, or plain text document—where each item is on its own line, and joins them into a single line where each value is separated by a comma. It's commonly used when formatting data for use in CSV files, array inputs, SQL `IN()` queries, or configuration lists in scripts and programming.

Why Convert Column Text to a Comma-Separated List?

Data preparation: Quickly prepare list data for Excel, CSV imports, or Google Sheets.
Web development: Easily format values for dropdowns, select fields, or form prepopulation.
SQL scripting: Convert lists into usable arrays for `WHERE IN (...)` queries.
Text processing: Clean and normalize inputs for use in APIs or configuration files.
Emailing or tagging: Transform a column of emails, usernames, or tags into one line for pasting.

How to Use This Tool

Paste your column of items into the input field.
Click the "Convert" button or watch as the result updates automatically.
Copy the resulting comma-separated list from the output field.
Use the formatted result in your spreadsheet, code, or tool of choice.

Our tool trims whitespace, ignores empty lines, and automatically handles common edge cases like trailing commas.

Example Input and Output

Input (Column):

Apple Banana Orange Mango
