JSON

Last modified: 10 August 2022

Required plugin: JavaScript and TypeScript

The plugin is available only in IntelliJ IDEA Ultimate, where it is enabled by default.

The JSON format is commonly used for storing data and for configuration files. IntelliJ IDEA helps you work with JSON files — it checks their syntax and formatting. In popular types of configuration files, IntelliJ IDEA provides code completion, thanks to the JSON Schema, which is a special format for describing the structure and contents of such files. You can also use custom JSON Schemas to enable code completion in your JSON files and validate them.
