Comma Separator

About This Tool

I built this comma separator because I got tired of manually formatting lists. You know the drill—copying a bunch of names, numbers, or items from a spreadsheet or email, and then having to go back and add commas between each one. It’s tedious. And honestly, kind of annoying when you’re in a hurry.

So I made something simple. Paste your text, hit a button, and boom—commas where they should be. No login, no ads, no nonsense. It just works. Whether you’re prepping data for a CSV, cleaning up a list for a script, or just trying to make your notes look less like a wall of text, this tool saves a few minutes you’ll actually notice.

It’s not fancy. But it does one thing well, and that’s enough.

FAQ

Does this work with numbers and special characters?
Yep. Whether it’s product codes, email addresses, or a mix of text and numbers, it treats each line or space-separated item as a separate entry and adds commas between them. Just paste and see.

What if my list has extra blank lines or weird spacing?
No problem. The tool ignores empty lines and cleans up extra spaces automatically. You’ll get a clean, comma-separated list without the junk.
