Altova XMLSpy is a leading XML editor and integrated development environment (IDE) designed for creating and manipulating XML-based applications. It offers a comprehensive suite of tools for working with XML, JSON, XBRL, schemas, transformations, web services, and more. XMLSpy empowers developers to visually design schemas, edit and debug code, generate code from schemas, and leverage AI-assisted editing and debugging for enhanced productivity.
The XMLSpy 2026 update introduces a BSON editor that provides developers with the same level of intelligent editing and control they’re accustomed to when working with traditional JSON documents. BSON (Binary JSON) is a binary-encoded serialization format that extends JSON to support additional data types and faster encoding/decoding. This enhancement allows creation, validation, and transformation of BSON data within a familiar interface, supporting native BSON datatypes and enabling direct schema validation, conversion between formats, and data generation from JSON Schemas. By extending XMLSpy’s JSON editing capabilities to BSON, developers can efficiently manage MongoDB data structures with greater precision and productivity.
