How to format JSON

Pretty-print

{"name":"Ada","skills":["math","logic"]}

{
  "name": "Ada",
  "skills": [
    "math",
    "logic"
  ]
}

Does this validate JSON too?

Yes. If the JSON is invalid, you get the error message with a line and column hint where possible.

Is my JSON sent to a server?

No. Formatting and validation happen entirely in your browser.

Can I sort object keys?

Yes. Turn on key sorting to order keys alphabetically at every level, which is handy for diffs.

What indentation can I use?

Two or four spaces for readable output, or minify to strip all whitespace for the smallest size.
