The Data Duel How JSON Unseated XML
Why JSON Took Over the API World: JSON vs XML Explained in Plain Language
This video breaks down why modern APIs overwhelmingly prefer JSON instead of XML, and how this shift transformed software development from SOAP to REST and now GraphQL.
We start with XML, originally built in the late 90s for structured documents. XML is powerful for validation, structured content, and complex enterprise needs. But it comes with heavy baggage: verbose tags, large payloads, and slow parsing. Developers had to work inside a tree structure first, then map that into real-world objects in code — a frustrating mismatch.
JSON flipped the model. It mirrors the object structures developers use daily. JSON is lighter, cleaner, faster to parse, and perfectly suited to the demands of web and mobile apps. That shift drove REST’s rise and helped push SOAP toward legacy status.
Then we move into GraphQL, which pushes API efficiency even further by letting clients ask for exactly the data they want and nothing more. It solves over-fetching and under-fetching, making JSON even more central as APIs evolve.
We also cover querying JSON inside databases, from SQL++ (designed for JSON in and JSON out) to SQL 2016 (traditional SQL plus JSON functions). The two models treat JSON very differently, especially around missing fields and nested data.
If you’ve ever wondered why JSON became the default for nearly everything, this video gives you the history, the technical reasons, and where things are headed next.
