What Is JSON?
JSON, or JavaScript Object Notation, is a lightweight text format commonly used for storing and exchanging structured data. It is widely used by websites, applications and APIs.
JSON uses objects, arrays, strings, numbers, booleans and null values to represent structured information.
Why Validate JSON?
Invalid JSON can cause errors when data is processed by websites, applications or APIs. Validating JSON before using it can help identify syntax problems such as missing commas, incorrect quotation marks or unmatched brackets.
