XML ValidatorBuddy for Windows

XML and JSON editor and validator with support for W3C schema, DTD, Schematron, JSON schema and much more.

The XML ValidatorBuddy desktop application offers a lot of XML related functionality for your daily work with XML documents. Beside powerful editors for XML and JSON, the tool includes an enhanced File Explorer and a Large File Viewer to give you convenient access to all of your XML and JSON data. The File Explorer shows detailed information about XML instance and schema files without the need to open them manually. This makes working with XML files more productive by saving time and clicks. For folders with a large number of files, XML related information is loaded in the background while the application is still responsive to user interaction.
