Use a JSON toolkit to inspect, format and validate structured data during development

JSON represents objects, arrays and scalar values used widely in APIs and application configuration.

Formatting and validation can make data easier to inspect, but syntactically valid JSON may still violate an application's expected schema.

Useful JSON workflows

  • Format compact API responses.
  • Validate JSON syntax.
  • Inspect nested objects and arrays.

What to verify

  • Check required fields separately from syntax.
  • Review numeric and null values.
  • Do not paste production secrets into tools unless appropriate for the environment.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
