JSON Scraper & Playground

Detect, format, and validate JSON right from any page instantly.

The Problem: The "Context-Switching" Tax As a developer, you live in the browser, but you spend half your time fighting it. When you need to inspect an API response or a data-heavy script tag, you are forced into a repetitive, inefficient workflow: Copy the messy, minified JSON string. Switch to an external tab (JSONLint, Postman, or a random formatter site). Paste and wait for the page to load. Repeat every time you need to check a slightly different value. This context-switching destroys your "flow state" and forces you to move sensitive API data to third-party servers just to make it readable. The Solution: JSON Scraper & Playground JSON Scraper & Playground brings the power of a professional API workbench directly into your toolbar. It keeps you in your IDE or browser tab, turning passive data viewing into an active, productive workspace. Key Features: Auto-Detection: Automatically scans the current page for JSON blobs hidden in <pre>, <code>, or <script> tags. One-Click Formatting: Instantly turn minified, unreadable JSON into clean, pretty-printed code. Built-in Playground: Don't just view data—test it. Use our side-panel playground to parse, validate, and manipulate JSON without leaving your current page. Comparison Mode: Highlight differences between two JSON snapshots side-by-side. Perfect for debugging API changes or data-state updates. Privacy-First: All processing happens locally in your browser. Your data never leaves your machine. Why Developers Love It Zero Tab-Switching: Save minutes every hour by staying in your workspace. Offline-Ready: Works perfectly without needing an internet connection.
