Edit and format JSON with ease

JSON Schema Linter

The main purpose of the JSON schema linter is to catch issues and critical errors in schema specifications early and automatically. This helps to increase the quality of the schema pool and to avoid breaking the work-flow. The linter reports issues, which are not covered by the standard schema validation. As an example, a broken $ref link, or missing definitions are detected and can be fixed immediately.

This JSON schema linter page is a simple showcase of the live analyzer available in JSONBuddy. The linter, available using the web form, offers the complete functionality but is currently limited to schemas and input with less than 2 KB of text. You can find a list of currently detected issues by the schema linter here

At this page, the WebAPI is accessible without any authentication. Using the API for testing, any input data is limited to 2 KB of size.

A full version of the WebAPI, with no size limitations, is available at the following RapidAPI page: JSON Toolbox The JSON WebAPI toolbox allows to run the JSON schema linter, pretty-print, minify and to apply JSONPatch operations to your JSON data.
