JSON Tools and Validation Guide

JSON Schema provides a contract for your JSON data, ensuring it meets specific requirements. It defines the structure, data types, required fields, and validation rules for your JSON documents.
Validate data structure and types automatically
Enforce required fields and constraints
Document your API contracts clearly
{
"type": "object",
"properties": {
"name": { "type": "string" },
"age": {
"type": "integer",
"minimum": 0,
"maximum": 120
}
},
"required": ["name"]
}
