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.

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.
