About JSON Validation
JSON (JavaScript Object Notation) is a lightweight data interchange format that must adhere to specific syntax rules. Validation ensures your JSON is well-formed, preventing errors when using it in applications, APIs, or configuration files.
Common JSON Validation Errors:
- Missing or mismatched brackets and braces
- Missing quotation marks around property names
- Trailing commas in arrays or objects
- Using single quotes instead of double quotes
- Including comments (JSON doesn't support comments)
