JSON Formatter
Format, minify and validate JSON for easier reading.
Processed on this page. No uploads. Your input is not saved.
How to use
Paste valid JSON, then format or minify and copy the result. Original number precision, key order and duplicate keys are preserved. Only whitespace outside strings changes; content is never executed. Supports up to 100 nesting levels.
Make JSON easier to review
Paste valid JSON, format it for reading or compact it for copying. If parsing fails, correct the source and try again; the tool does not guess missing data.
Example and expected result
The compact JSON {"name":"Robin","count":2} becomes an indented object when formatted and returns to compact form when minified. Comments, trailing commas and single-quoted strings are not valid JSON. Formatting is not schema validation.
