About JSON Formatter DevKit
An all-in-one JSON Formatter, Viewer, and HTTP Header Injector designed specifically for developers!
JSON Formatter DevKit transforms raw JSON content into a clean, readable, syntax-highlighted, and collapsible tree structure directly inside your browser. It also streamlines your API testing and web development workflows with advanced utility features.
Key Features:
1. Fast JSON Formatter: Instantly beautify large JSON documents with collapsible nodes, syntax highlighting, and an integrated search.
2. Custom HTTP Header Injector: Modify and inject custom HTTP headers (such as API keys, authorization tokens, or custom User-Agents) for designated URL patterns.
3. Network Timing & Request Inspector: Capture page load times, HTTP status codes, and request/response headers directly from the extension popup.
4. Safe & Private: Operates entirely client-side. No data is collected or sent to external servers.
