Is JSON a standard format?

Yes, JSON is an official standard format defined by RFC 8259, published by the Internet Engineering Task Force (IETF) in December 2017. This specification defines JSON syntax, structure, and requirements precisely, ensuring consistency across implementations. JSON is also standardized as ECMA-404 by Ecma International. These standards describe valid JSON data types, syntax rules, character encoding requirements, and parsing guidelines. The standardization ensures JSON works identically across all platforms, programming languages, and systems. This universal standard is why JSON has become the dominant data interchange format for web APIs, configuration files, and data storage. Following the standard guarantees your JSON will be compatible with all compliant parsers and tools. Our JSON tools at jsonconsole.com strictly follow these standards, ensuring your JSON is valid and compatible with any system that implements the JSON specification correctly.
