JSON Editor

JSON Editor is a tree & text editor for JSON, JSON5 and JSON Lines data formats. In a clean and user-friendly interface, it allows you to create, visualize, modify, validate, format and save your JSON documents.

Along with the included HTTP Client, is a powerful tool to inspect and debug your API endpoints.

JSON Editor has the smarts needed to make the minimum changes when editing a file, even in the tree mode.

This is especially useful when you keep the files in a repository, because only the relevant changes will be shown when diff-ing the edited files.

JSON Tree Editor

• Presents the JSON in a "tree" like interface, making easier to understand how the data is structured

• Makes the process of editing JSON data error-free and way more easier than dealing with raw text

• Its selection is automatically reflected in the text editor
