About JSON Formatter Pro

JSON Formatter Pro – Smart JSON Viewer, Search & Export Tools In 2026, handling JSON data doesn’t have to be a hassle. JSON Formatter Pro is a browser extension that automatically detects and formats JSON data on webpages, turning raw responses into a clean, interactive viewer. Instead of reading unformatted JSON, you can explore data in a structured tree view that makes nested objects and arrays easier to understand. This helps when reviewing API responses, debugging data, or inspecting JSON documents directly in the browser. 🚀 Key Features Automatic JSON Detection Automatically detects JSON responses on supported pages and opens them in a structured viewer. Supports: • API responses • JSON documents • REST endpoints • <pre> formatted JSON pages Interactive Tree View Browse JSON data in an expandable and collapsible tree layout. This makes it easier to: • read nested objects • collapse large sections • inspect complex responses Search Inside JSON Search keys and values within large JSON responses. You can: • find specific fields quickly • highlight matching results • move through large datasets more easily JSON Path Generator Generate JSONPath for selected nodes to help with inspection and debugging. Copy Tools Copy useful data directly from the viewer, including: • key • value • path • object Pinned Nodes Pin important fields for quicker access while inspecting large responses. History Tracker View recently opened JSON responses with details such as: • page URL • JSON size • timestamp Export Options Export JSON into other useful formats: • YAML • CSV Size Analyzer See response size information such as bytes, KB, or MB for quick payload inspection. Dark and Light Theme Choose the appearance that feels most comfortable during use. Works Across Websites Use the extension on supported webpages that return JSON content, including local development environments. Lightweight and Fast Designed to stay responsive while viewing large JSON responses. Privacy JSON Formatter Pro does not collect or sell personal data. Processing happens locally in the browser. Why Use JSON Formatter Pro JSON Formatter Pro helps make raw JSON easier to read, search, inspect, and export without leaving the page. The main issue was the “Who Should Use This Extension” section because Chrome Web Store often treats role-stuffing as keyword spam. Remove that whole block and keep the description focused on actual functionality.
