XML and JSON in 2026

11 hours ago

JSON celebrates its 25th birthday and remains unchanged due to widespread use in billions of devices, with its official RFC immutable and no plans for updates, despite known limitations like lack of comments and number type distinctions.
XML is considered largely obsolete by some but succeeded in proving key computing principles: data interchange independence and Unicode adoption, and it still sees use in areas like office documents, humanities computing, legislation, and specific industries like aerospace and business (e.g., UBL).
Comments from readers highlight XML's continued relevance in sectors like aerospace, defense, and business, while critiquing its misuse for configurations and languages, and noting JSON's dominance in modern applications like AI, with both technologies now often taken for granted.
