The JSON Schema standard is used to describe any data format for JSON in a similar way XML Schema is used for XML. At the same time JSON Schema provides a human- and machine-readable documentation for JSON content. The standard supports complete structural validation as well as data type checking. JSON Schema is also often used to validate client-submitted data especially for JSON based web services.

The complete JSON schema specification as interactive help-text

JSONBuddy displays the text of the full JSON schema specification for every keyword if you hover the mouse over it. This helps a lot if you are not sure about the definition or purpose of any JSON schema keyword and increases productivity. The JSON schema specification is well written and gives a good idea when and how a keyword shall be used. So it is a big help if you have it available directly in your editor.

You can also validate your JSON schema document in JSONBuddy with a single click. Just use the "Validate against JSON schema" command (usually F11) to validate your schema in the editor.

Live preview of JSON schema sample data

The editor will immediately start to generate a live preview of JSON sample data matching the current schema definitions. This sample data is then shown in the Preview pane. You can see the generated JSON data with the section highlighted, which is related to the schema part currently selected in the editor window. The sample data is automatically updated in the background if the schema is modified.

You can also create a new document with the current JSON sample data with the “JSON | Generate sample document from JSON schema” command.
