JSON Schema Conformance Tool

Validates JavaScript Object Notation (JSON) data streams.

How to Use JSON Formatter & Validator:

  • Paste your JSON data into the "Input JSON" box.
  • Choose formatting options:
    • Indent Size: Select the number of spaces for indentation (2, 4, or 8).
    • Minify: Check this box to remove all whitespace and output compact JSON. Overrides Indent Size.
    • Sort Keys: Check this box to sort the keys within JSON objects alphabetically.
  • Click "Format / Validate". The tool will first validate the input.
  • If valid, the formatted or minified JSON appears in the "Result" box, along with statistics.
  • If invalid, an error message detailing the issue (including line and column) will be shown in the feedback area.
