About this tool: JSON Formatter
Validate, indent or minify JSON. Numbers use JavaScript precision.
Formatting helps inspect API responses and configuration files by separating nested objects and arrays. Minification removes presentation whitespace without changing the parsed structure. Invalid JSON is rejected; large numbers follow JavaScript’s numeric precision, so identifiers beyond safe integer range should be strings.
How the calculation works
Worked example
| Input | {"name":"Asted","tools":[1,2,3]} |
| Mode | Format |
| Indentation | 2 |
{
"name": "Asted",
"tools": [1, 2, 3]
