Frequently Asked Questions

Everything you need to know about converting comma-separated text to columns. Can't find what you're looking for? Contact us.

A comma to column converter takes a comma-separated list of values and splits each item onto its own line. Instead of a single line like "Toronto, Vancouver, Montreal", you get a clean column with one city per row. It is the fastest way to reformat CSV data, email lists, or any delimited text into a vertical list for spreadsheets, databases, or further processing.
Paste your comma-separated text into the input box, make sure the separator is set to a comma (the default), then click "Convert to Column". Each item will appear on its own line in the output box. You can then copy the result to your clipboard with one click or download it as a .txt file for use in other applications.
Yes. You can change the separator to any character you like — semicolons, pipes (|), tabs, colons, dashes, or any custom string. Simply type your desired separator into the Separator field before clicking Convert. This makes the tool work with virtually any delimited text format you encounter.
Yes, this comma to column converter is 100% free with no limitations whatsoever. There are no hidden charges, no premium tiers, and no sign-up required. You can process unlimited amounts of text as many times as you need without ever creating an account or providing personal information.
Absolutely. All text processing happens entirely in your browser using client-side JavaScript. Your data is never transmitted to any server, stored in any database, or shared with any third party. When you close the page, all data is gone — your privacy is fully protected at all times.
Yes, by default the tool trims leading and trailing whitespace from each item after splitting. This means "apple, banana, cherry" will produce clean lines without extra spaces. You can disable this behaviour by unchecking the "Trim whitespace" option if you need to preserve original spacing in your data.
Yes! CoderDesign offers a companion Column to Comma tool that does the reverse — it takes a list of items (one per line) and joins them back into a single comma-separated string. Together, the two tools give you complete control over converting between horizontal and vertical list formats.
You can upload plain .txt files directly using the "Upload .txt file" button. The tool also accepts pasted text from any source — spreadsheets, code editors, emails, or web pages. After processing, you can download the column output as a .txt file ready for use in any application.
