About JSON Validate
JSON Validator checks whether your payload parses cleanly. When something is wrong, you get a clear error instead of a silent failure later in the pipeline. Use it beside the formatter when you only need a pass/fail check.
Frequently asked questions
No. It only reports whether the text parses.
Common issues like missing commas, trailing commas, unquoted keys, and truncated strings.
Nowhere off your machine - validation runs in the browser.
