Advanced tools for editing, converting, and generating JSON
While many online JSON editors are available for quick tasks, for advanced functionality and when JSON editing is a common requirement, a software download like XMLSpy is preferable. XMLSpy includes options for text and graphical editing, JSON Schema generation, conversion between XML and JSON, and more.
XMLSpy includes JSON Grid, which offers a graphical representation of the JSON document structure that is immediately easier to understand than the corresponding code in text view, especially for long, complex documents with multiple nested levels of arrays and objects. JSON Grid also has powerful editing features including:
Of course, XMLSpy also includes text-based JSON file editor with syntax coloring, line numbering, source folding, bookmarking, and more, making it easy to navigate and understand your JSON code, and find and edit strings. When you enable intelligent editing in the XMLSpy Info window, the Elements entry helper window provides a dynamically built list of the elements present in your document. You can insert an element from the Elements window by double clicking it, or by dragging it into your document in the editing pane.
Syntax checking and JSON Schema-based validation guide you in making valid edits. Any errors are listed in the multi-tabbed Messages window, which also includes a hyperlink to the error in your document and the related schema, making trouble-shooting a breeze.
XMLSpy supports JSON as well as JSON5, JSON lines, and JSON with Comments (.jsonc).
By default, XMLSpy recognizes files with the .json file extension as JSON instance documents, and those with the .json5 file extension as JSON5 instance documents.
Converting XSD to JSON Schema is also supported.
Unlike basic online tools, the XMLSpy JSON editor download for Windows gives you all the advanced tools described above, in one version. It takes just a few minutes to install the softare - and there is no credit card required to activate your fully functional, 30-day trial.
