JSON Beautifier
Turn compact or messy JSON into clean, indented, human-readable form. Also normalizes whitespace so diffs stay stable.
Frequently asked questions
What is the difference between beautify and validate?
Beautifying re-formats valid JSON for reading; validation only checks syntax. This tool does both in one step: if the input is invalid it refuses to reformat and shows the error instead of producing broken output.
Does beautifying change my data?
No. Re-formatting only changes whitespace — every string, number, key and order stays exactly the same. The output is guaranteed to parse to an identical value.
Which indentation does it use?
Two spaces per level, the convention used by most style guides and prettier's default. If you need tabs or 4 spaces, copy the output into our JSON Formatter and pick your preference there.
