Paste JSON below and click "Check & Suggest Fix" in the toolbar to validate it. If it’s valid, you’ll see whether it parsed as an object or an array (and how many items). If it’s invalid, you get the exact line and column of the problem.
This catches the errors that are hardest to spot by eye: a missing comma, an extra trailing comma, or an unclosed brace buried in a large payload.
Yes - errors are reported with line and column numbers whenever the underlying parser provides a position, so you don’t have to scan the whole document manually.
No - this validates JSON syntax (that it parses correctly), not structural rules like required fields or types. For that you’d need a JSON Schema validator.
