Paste compact JSON and beautify it into clean, readable, properly indented output — right in your browser.
Formatted JSON will appear here after you click Format.
Beautifying JSON means adding consistent indentation and line breaks so a document is easy for people to read. Only the whitespace and layout change — the keys, values, ordering, and data types stay exactly the same. It is the opposite of minifying, which strips whitespace out.
“Beautify” and “format” describe the same operation: pretty-printing JSON. If you prefer that term, the JSON Formatter is the same tool under a different name.
Compact JSON on the left, beautified with two-space indentation on the right.
{"user":{"id":1,"name":"Ada"},"roles":["admin","editor"]}{
"user": {
"id": 1,
"name": "Ada"
},
"roles": [
"admin",
"editor"
]
}Beautifying JSON means re-formatting it with consistent indentation and line breaks so it is easy to read. The data itself is unchanged — only the whitespace and layout are adjusted.
They do the same core job: turning compact JSON into readable, indented JSON. "Beautify" and "format" are different names for pretty-printing. This site offers both under names people search for; both use the same engine.
No. Beautifying only affects formatting (spaces and newlines). Keys, values, order, and types stay exactly the same.
Yes. The tool parses your input first, so if it beautifies successfully the JSON is valid. If it is invalid, you'll get a clear error with its line and column.
No. Beautification happens entirely in your browser; your data never leaves your device.
