About

Create, edit, transform, and debug XML and JSON documents with Altova XMLSpy 2026 Enterprise Edition. Its graphical schema designer supports modeling, while code generation and file conversion tools help prepare data and related development files.

The Windows x64 application includes debuggers and profilers for XSD, XSLT, XQuery, XBRL, SOAP, and other related technologies. Developers can use it to work with schemas, inspect transformations, and debug XML- and JSON-based projects in one environment.

Version 2026.02.00 keeps a node’s collapsed state when it is copied and pasted in Grid View. It also addresses the XSLT debugger error that occurred when starting a debugging session with a JSON file as input. Altova publishes the software.
