Frequently Asked Questions
What does the JSON validator check?
It checks for proper JSON syntax including matching brackets, correct string quoting, valid data types, and proper comma placement.
Can it validate JSON Schema?
This tool validates JSON syntax. For JSON Schema validation (checking if JSON matches a specific schema), you would need a dedicated schema validator.
What is the difference between JSON validation and formatting?
Validation checks if your JSON is syntactically correct. Formatting takes valid JSON and adds indentation and line breaks for readability.
