How it works

  1. Select local JSON files in File Explorer.
  2. Press Alt + Space and type “Validate JSON”.
  3. Run the check; it validates JSON syntax, not a custom schema or business rules.
  4. Start the action and check the result.

A practical example

Check whether a hand-edited JSON file still has valid brackets and commas.
