JSON Formatter - Paste and Done

👉 JSON Formatter

Got an API response in one long line... can't read a thing

When You Need to Format JSON

If you code, this happens daily:

• API responses → one giant unreadable line
• Config files → can't tell where brackets close
• Debugging → console output is a mess
• Code review → checking JSON data from teammates

Developers format JSON at least once a day.

The Usual Options Suck

• VS Code → create new file, change extension, format shortcut... too many steps
• Google it → ad-filled sites, slow loading
• Chrome console → typing JSON.parse every time is tedious
• Postman → great tool, but heavy just for formatting

Just want to paste and see it formatted. Instantly.

So I Built One

One paste, instant result.

Core features:

• Beautify → adds indentation for readability
• Minify → strips whitespace to reduce size
• Auto-validation → shows error location if syntax is wrong

Extras:

• Adjustable indentation (2 or 4 spaces)
• Copy to clipboard
• Error position highlight

After Actually Using It

Pros:

• No ads, no loading time
• Results appear the moment you paste
• Error location pinpointed → saves debugging time

Limits:

• Multi-MB JSON files might slow down the browser
• For those, CLI tools like jq are better

Great to keep open in a tab while debugging APIs.
