About
JSON Toolbox is a free and open-source Chrome extension for developers who work with JSON. It detects raw JSON responses in the browser and replaces them with a readable interactive tree view. It also includes a full editor for formatting, minifying, sorting keys, extracting JSON paths, generating TypeScript types, and copying formatted JSON. All processing happens locally in the browser. JSON data is not sent to any external server.
