JSON Formatter
Format and beautify JSON data for improved readability and easier debugging with this tool.
How the JSON Formatter works
Use the JSON Formatter to organize unformatted JSON data. This tool takes raw JSON text and restructures it into a human-readable format.
First, paste your JSON data into the "JSON" input box. The tool accepts JSON objects, arrays, or snippets. After you paste the data, the tool automatically processes it. It adds appropriate indentation and line breaks. The formatted JSON then appears in the output area. You can copy this formatted output for use in your projects or for easier review. This helps in identifying errors or understanding data structures quickly.
Formula used
JSON.parse → JSON.stringify with an indent of 2 spaces
| Symbol | Meaning |
|---|---|
| input | a JSON object, array or snippet |
Formatting is done with the browser’s own JSON parser, so you get a real syntax error with the exact position instead of a guess. Your data never leaves the page, which matters for API responses and config files.
Inputs used: JSON.
Worked example
Here is an example of formatting a JSON string.
- Input the following unformatted JSON into the "JSON" text area: {"site":"ToolFactory","tools":[{"id":"emi-calculator","type":"CALC"}],"live":true}
- The tool will automatically process the input.
- The output will display the formatted JSON: { "site": "ToolFactory", "tools": [ { "id": "emi-calculator", "type": "CALC" } ], "live": true }
Result:
- output: { "site": "ToolFactory", "tools": [ { "id": "emi-calculator", "type": "CALC" } ], "live": true }
