About

JSON Text Validator is a lightweight Chrome extension that lets you validate highlighted JSON text directly from any webpage.

Benefits:  
- Save time by integrating validation directly into your browsing experience. 
- Eliminate the hassle of switching between tabs or using online validators. Highlight, click, and get results instantly.

Features:
- Validate JSON by simply highlighting text and right-clicking.
- Detect errors and view detailed feedback instantly.
- No need to copy and paste JSON into external tools.
- Works on most webpage, making it convenient for developers and analysts.
- Lightweight and fast, with minimal system resource usage.

Permissions:
- Context Menus: This extension uses the contextMenus permission to add a right-click menu option, making it easy to validate JSON directly from any webpage.
- Active Tab: The activeTab permission allows the extension to access the currently active webpage when you use the extension. This is necessary to read and validate highlighted JSON without requiring broader permissions.

Your privacy is important—this extension only interacts with the page when you activate it and does not collect or store any data.

disclaimer: 
Some websites prevent extension from modifying the DOM(Document Object Model), which prevent the extension from showing validation the result as popup toast. Should you find any problem with this extension we appreciate if you let us know.
