Step-by-step
- Copy the JSON you need to inspect.
- Open the DevUtilityKits JSON Formatter.
- Paste the JSON into the editor.
- Format the data and review the result.
- If validation reports an error, check the indicated area and correct the JSON.
Why format JSON?
Readable JSON makes nested objects, arrays, keys, and values much easier to inspect. This is especially useful when an API returns JSON on one long line.
Formatted JSON does not change the data
Pretty printing normally changes whitespace and indentation rather than the meaning of the JSON. A formatter should not silently change keys or values.
Common formatting problems
Missing commas, unmatched braces, invalid quotation marks, and trailing commas are frequent causes of invalid JSON.
