A web-based JSON editor library to view, edit, format, repair, compare, query, and validate JSON, usable as an embeddable component in web applications. It offers tree, code, text, and table modes with JSON Schema validation, and has a successor library, svelte-jsoneditor.
Use cases
- edit and format JSON in the browser
- embed a JSON editor component in my web app
- validate JSON against a JSON Schema
- repair broken or malformed JSON
- compare two JSON documents and highlight differences
- view large JSON files in a tree or table view
- query and transform JSON with JMESPath
When to choose
- you need an embeddable, feature-rich JSON editor in a JavaScript web application
- you need tree, code, text, and table views with schema validation and JSON repair
- you want a mature, widely used editor backed by the jsoneditoronline.org web app
When to avoid
- you are starting a new project - prefer the successor svelte-jsoneditor
- you need a native desktop or CLI JSON tool rather than a browser-based editor
- you need a framework-agnostic or non-JavaScript solution
