JSON Editor: Grid View
A revolutionary, first-of-its-kind JSON editing environment is provided by XMLSpy JSON Grid View. JSON Grid provides a graphical representation of the JSON document structure that is immediately easier to understand than the corresponding JSON code in text view, especially for long, complex documents with multiple nested levels of arrays and objects. Advanced features such as automatic type detection, in-cell commands, XQuery filters for modifying the view, XQuery formulas for generating additional output from the JSON data, and more, combine to make JSON editing faster and easier than a text-based JSON editor. JSON Grid even allows you to create charts from JSON data.
In addition to utilizing XQuery for filters and formulas in JSON Grid, you can use it to create charts from numerical JSON data.
Create charts using JSON data
After configuring a chart function, the save icon embeds the chart in the JSON file as a base-64 encoded image. Or, simply right-click on the chart to save it in an image file such as .png or .jpg.
No other JSON editor offers anything even close to this functionality!
JSON Schema Editor
XMLSpy has full support for generating and editing JSON Schema
Just as XMLSpy pioneered the first graphical XML Schema editor, it now also includes the first enterprise-grade, graphical JSON Schema editor to greatly speed schema generation, development, and validation for developers working with JSON.
JSON Schema View will be immediately familiar to XMLSpy customers who’ve used XML Schema View and are now learning to design JSON Schemas, while at the same time being easy to comprehend for new users. Use the JSON Schema editor for:
- Drag-and-drop JSON Schema editing & validation
- XML Schema <=> JSON Schema conversion
- Generation of JSON instance files from JSON Schema
- JSON Schema documentation generation
- Querying & Transforming JSON with XPath, XSLT, XQuery
Despite the growing popularity of JSON, there isn’t a widely used language for querying and transforming JSON data. Luckily, functionality added to XPath/XQuery 3.1 provides a means for targeting JSON maps, arrays, and objects, offering a standardized way to query and transform JSON data using these familiar languages.
XMLSpy makes it easy to process JSON documents with XPath, XSLT, and XQuery using intelligent editors and the interactive XPath/XQuery Builder & Evaluator Window. Functionality includes:
Querying JSON documents with XPath 3.1 or XQuery 3.1 in the XPath/XQuery window
Transforming JSON documents with an XSLT 3.0 or XQuery 3.1 file
Querying JSON with XPath/XQUery
Learn How to Query JSON with XSLT and XPath/XQuery
XSL and XSLT Tools
XMLSpy includes numerous tools for XSLT development and debugging
The JSON and XML Editor provides complete support for XSL and XSLT development in its XSLT editor with context-sensitive entry helpers, an XSL outline window, and more.
For transformation, seamless integration with installed RaptorXML Servers delivers hyper-performance functionality coupled with strict conformance to W3C standards, including XSLT, XPath, and XQuery versions 1.0, 2.0, and 3.1. This allows you to take advantage of super-fast transformations during development and testing, all directly inside XMLSpy.
XMLSpy even includes intelligent HTML / HTML5 and CSS / CSS3 editors along with an integrated browser view.
XSLT Debugger and Profiler
The XSLT debugger in the XML editor helps you track down XSLT errors
The XMLSpy XSLT profiler is an invaluable tool for optimizing the performance of your XSLT code. Based on the information revealed by the XSLT profiler, you can immediately see which parts of your XSLT code are taking the most time to process and adjust them accordingly to fully optimize your XSLT stylesheets.
XSL Speed Optimizer
The XSLT profiler delivers important information for expert XSLT developers, but if you want to speed up XSLT execution time without manually changing your XSLT and XPath code, try the XSL Speed Optimizer.
The XSL Speed Optimizer in XMLSpy is a revolutionary, patented approach to speeding up XSLT transformations, providing tremendous increases in throughput with no manual analysis required to determine exactly which XSLT or XPath expressions are causing bottlenecks.
XSLT and XQuery Back-mapping
XMLSpy includes XSLT back-mapping for debugging your transformations
Because XSLT and XQuery documents are frequently long and complex, it can be difficult to identify the source of unintended output. For targeted debugging, back-mapping makes it easy to immediately correlate output elements to source nodes and instructions.
With back-mapping enabled, XSLT transformations and XQuery executions are carried out so that the result document can be mapped back on to the originating XSLT+XML or XQuery+XML documents. When you click on a node in the result document, the XSLT instruction and the XML source data that generated that particular result node will be highlighted.
Back-mapping in XMLSpy is revolutionary in two ways. First, it saves developers considerable time in debugging, refining, and perfecting their code as well as understanding inherited code written by other team members. Second, XMLSpy does not make any changes or add additional code to the output document in order to achieve back-mapping.
XPath and XQuery Tools
XMLSpy provides intelligent tools for building XPath expressions
The XPath and XQuery window makes it easy to build and test your XPath/XQuery expressions as you compose them with built-in Builder and Evaluator windows. Helpful functionality to speed development is provided through:
- XPath builder and tester

Support for schema-awareness in the XQuery editor allows you to harness the full power of XQuery through mechanisms for error isolation, simplified debugging, and enhanced code performance.
The powerful XPath and XQuery window also includes a powerful Debugger for testing, troubleshooting, and perfecting your XPath/XQuery to save time and reduce frustration.
The debugger lets you go step-by-step through the evaluation of your XPath or XQuery expression. Each click shows you the results for the corresponding step of the evaluation, and you can step into, step out, and step over evaluation steps using helpful buttons in the debugger toolbar.
The XPath and XQuery debugger in XMLSpy help you perfect your code
An advanced XQuery Profiler is also provided, helping you analyze and optimize your XQuery code performance.
Targeted debugging is also provided via XQuery back-mapping.
XQuery Update Facility Editor
The XPath/XQuery window in the XML Editor also supports editing XQuery Update (XQU) Facility 1.0 and 3.0 statements with advanced functionality for composing XQuery Update Facility expressions with full syntax coloring, intelligent code completion, and error message reporting.
The results pane lets you preview the results of the changes, and clicking on a result in the preview pane highlights the affected node in your instance document. Then, you can execute the updates with one click, either in the current file or across all open files, a folder, or an entire XMLSpy project. This functionality is unique to XMLSpy.

Compare JSON and XML Documents
XMLSpy includes powerful diff/merge tools to compare JSON documents and other text files, as well as directories. For file comparisons, 2- and 3-way comparisons are supported. Users can edit documents and merge changes in either direction.
For XML comparisions, the XMLSpy XML editor includes includes a visual XML compare tool that allows developers to easily compare XML and merge documents and directories in an intelligent, XML-aware manner.
The XML-aware diff/merge options are completely customizable. For example, you can specify if entities should be resolved, if namespace prefixes, whitespace, CDATA, processing instructions, comments, or the ordering of attributes/child elements should be ignored or not, and how to visualize differences. In addition, you can merge the textual differences and differences in XML between files as you are comparing them.
Compare XML with 3-way diff merge directly in the XML editor
