JSON formatter: inputs, results and limitations
Make valid JSON easier to inspect with indentation and clear nesting.
How to use JSON formatter
- Paste your text or use the example to inspect the operation.
- Run the tool once the input is ready.
- Inspect the preview or result, then download a new file.
An illustrative use case
A compact JSON object expanded into readable indentation.
Sample input
{"hello":"Tabaix","count":3}What to inspect in the output
Use strict JSON: double-quoted strings and property names, no trailing commas and no comments. Formatting does not check the domain-specific meaning of your object.
Where this tool stops
Review the output before using it. Your original input is not changed.
Troubleshooting JSON formatter
Check source syntax and distinguish literal characters from their escaped representation. Run the example first, then compare with your failing input to isolate the invalid part.
