What Is a Comma Separated List?

A comma separated list (also called CSV — Comma Separated Values) is a way of organizing data where each item is separated by a comma. For example: apple, banana, orange. This format is widely used in spreadsheets, databases, programming, and data exchange between systems.

When Do You Need to Convert Comma to Newline?

There are many scenarios where converting between comma separated and newline formats is useful. If you're working with Excel and need to paste a horizontal list into a vertical column, or if you're extracting data from a CSV file and need each value on its own line for processing, this tool handles it instantly.

Common use cases include preparing SQL IN clauses, formatting email lists, converting exported CRM data, cleaning up CSV files, and transforming data for import into different systems.

CSV Delimiter Issues in Different Regions

In many Latin American and European countries, Excel uses semicolons (;) instead of commas as the CSV delimiter. This is because these regions use commas as decimal separators (e.g., 3,14 instead of 3.14). This tool supports semicolons, pipes, tabs, and custom separators to handle these regional differences.

How to Use This Tool

Paste your text in the input box, select your separator, and click "To New Lines" to split the list into individual lines, or "To Comma Separated" to join lines back together. You can trim spaces and remove empty lines automatically. The swap button lets you quickly move the output back to the input for chaining transformations.

Frequently Asked Questions

How do I convert a comma separated list to new lines?
Paste your comma separated text in the input box and click "To New Lines." Each value separated by a comma will appear on its own line in the output. You can then copy the result with one click.
Can I use a different separator like semicolons or pipes?
Yes. Use the "Separator" dropdown to choose commas, semicolons, pipes, tabs, or enter a custom separator. This is especially useful for European and Latin American users whose Excel exports use semicolons instead of commas.
Does this tool store my data?
No. All processing happens entirely in your browser. Your text is never sent to any server, stored, or logged. You can verify this by using the tool offline after loading the page.
What's the maximum text size I can convert?
There's no hard limit. The tool runs locally in your browser, so it depends on your device. It comfortably handles tens of thousands of lines without issues.
How do I convert new lines back to a comma separated list?
Paste your multi-line text and click "To Comma Separated." Each line will be joined together with the selected separator (comma by default). Enable "Trim spaces" to clean up any extra whitespace.
