About

JSON File Manager Pro is a must-have extension for frontend and backend developers. Built on top of the Monaco Editor (the powerhouse behind VS Code), it brings a true IDE-like experience right into your Chrome popup or side panel.

Stop wrestling with syntax errors and unformatted API responses. Beautify, minify, compare, and convert your data with zero lag.

🚀 Pro Developer Features:

JSON to TypeScript: Instantly generate perfectly typed TypeScript interfaces from any JSON response.

Side-by-Side Diffing: Compare two JSON objects to easily spot additions, deletions, and modifications.

Smart String ↔ JSON Converter: Safely escape or unescape stringified JSON payloads without throwing annoying quote errors.

HTML ↔ JSON Converter: Transform raw HTML strings into structured JSON syntax trees (AST) and back.

VS Code Engine: Enjoy full syntax highlighting, bracket matching, and real-time error detection powered by Monaco.

🛠 Core Workspace Features:

1-Click Beautify & Format

1-Click Minify

File Manager: Save, edit, update, and delete your most-used JSON payloads to reuse them later.

Dedicated Split-Pane UI for Input and Output.

🔒 100% Offline & Private:
Your data is yours. All files and payloads are securely stored locally in your browser using Chrome Storage. No analytics, no tracking, and no data is ever collected or transmitted to external servers.
