Use JSON Validator
- You need to catch syntax errors.
- You are formatting pasted API output.
- You do not have a schema yet.
Tool comparison
JSON Validator vs JSON Schema Validator
JSON Validator checks whether JSON parses. JSON Schema Validator checks whether parsed JSON matches a separate schema contract.
Decision
Which one fits the task?
Use JSON Schema Validator
- You have a JSON Schema to test against.
- Required fields, types, enums, or object shapes matter.
- You need a stronger handoff signal than syntax alone.
Avoid
Common mistake
Valid JSON can still be the wrong shape. Schema-valid JSON can still be semantically wrong for your business rules.
Quality
Review before you finish
Quality notes
- Infer schema only as a draft from sample data.
- Flattening JSON can lose nested meaning if arrays are complex.
- Do not paste secrets or production tokens into browser tools unless your workflow allows it.
Next steps
- Validate syntax first.
- Infer or provide schema only after the JSON parses.
- Export to CSV or XLSX after the table shape is reviewed.
