How this service works
Pretty-print or minify JSON, optionally sorting keys, and report the size before and after.
Output
Returns the reformatted JSON string (pretty-printed or minified, with keys optionally sorted), plus the character count of the input before formatting and the output after formatting, allowing you to measure compaction or expansion.
Example use cases
Beautify API response for debugging
“I got this raw JSON back from an API call and it's all on one line — can you format it with 2-space indentation so I can read it? Here it is: {"user":{"id":123,"name":"Alice","roles":["admin","viewer"]}}”
Minify JSON for production payload
“Can you minify this JSON down to zero indentation so I can embed it compactly in my config? I also want to know how many characters it shrinks by: {"host": "localhost", "port": 5432, "db": "myapp"}”
Sort JSON keys for canonical representation
“Take this JSON object and reformat it with sorted keys and 2-space indentation — I need a deterministic, canonical form for checksumming: {"z":true,"a":"hello","m":42}”

Endpoint
GEThttps://json-data-tools.x402tookit.com/json-format?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to reformat, compress, or canonicalize a JSON string and also want to know the before/after size impact. It combines pretty-printing, minification, and key sorting in a single call, making it ideal for pipelines that need a consistent JSON representation or want to measure payload size reduction.
Side effects
- Invalid JSON input returns an error response rather than formatted output
- Extremely large JSON strings may time out or hit size limits
- Malformed query parameters (e.g. non-integer indent) may cause a 400 error
- Network or payment (x402) failures result in no response
