What is JSON and why is it everywhere?

JSON (JavaScript Object Notation) was proposed by Douglas Crockford in 2001 as a lightweight, human-readable data interchange format. By 2010 it had largely displaced XML as the dominant format for REST APIs. Today, virtually every web application, mobile app and cloud service uses JSON: Google Maps API returns location data in JSON, Stripe processes payments with JSON payloads, and GitHub's API exposes repository data in JSON. Its power lies in its simplicity — just six data types (string, number, boolean, null, array and object), a syntax any developer can read in 10 minutes, and direct mapping to native data structures in every major programming language.

Why JSON syntax errors are so costly in production

JSON has zero fault tolerance: a single misplaced comma, an unquoted key, a trailing comma after the last element, or an unclosed bracket causes a complete parse failure — typically resulting in a silent null value or an unhandled exception that crashes the feature. Our validator pinpoints the exact line and column of any error, making debugging 10× faster than reading raw minified output. Pair with our Base64 Decoder to decode API payloads and our Unix Timestamp Converter to interpret date fields.
