Comma Separator

About This Tool

So, I built this thing because I kept running into the same problem—copying a list of stuff from a spreadsheet or a database, and then realizing I needed it formatted with commas. Like, seriously, why isn’t there a one-click fix for this? I’d waste five minutes manually adding commas or wrestling with Excel formulas that never quite worked right. This comma separator? It’s dead simple. Paste your list—one item per line, or even mashed together—and it spits out a clean, comma-separated string. No fluff, no login, no “premium features.” Just a text box and a button. I use it at least twice a week, honestly. Whether I’m prepping data for a script, building a SQL query, or just tidying up a list for an email, it saves me time and sanity. It’s not fancy. But it works. And honestly, that’s all I wanted.

Key Features

• Takes messy input—line breaks, spaces, tabs—and turns it into a clean comma-separated list.
• Handles both vertical lists (one per line) and horizontal text (already separated by spaces or other junk).
• Removes extra whitespace automatically. No more trailing spaces or double commas.
• Optional: Add quotes around each item. Handy for CSV or code strings.
• Works entirely in your browser. Nothing gets sent anywhere. Your data stays yours.
• No ads, no tracking, no nonsense. Just a tool that does one thing well.

FAQ

Can I use this for large lists?
Yeah, it handles a few thousand items without breaking a sweat. Just don’t paste your entire company’s customer database and expect magic—common sense still applies.

Why not just use Excel?
You could. But Excel overcomplicates simple tasks. This is faster when you just need a quick comma list and don’t want to open a spreadsheet, format columns, and copy-paste again.
