- Tap Format for readable, indented JSON, or Minify to compact it.
- Copy the result from the output box.
Frequently asked questions
What happens if my JSON is invalid?
You'll see a clear error message explaining what's wrong, instead of a blank or broken result.
Is my JSON uploaded anywhere?
No — formatting happens entirely in your browser.
