JSON Viewer+ од rxliuli

JSON Viewer highlights JSON and JSONP content directly in your browser. When you open a URL that returns JSON, the extension automatically formats and syntax-highlights it.

This is a maintained fork of the original JSON Viewer by Tulio Ornelas, updated to work with modern browsers (Manifest V3).

Features:

• Syntax highlighting with 27 built-in themes
• Collapsible/foldable nodes
• Clickable URLs within JSON values
• Line numbers
• Search within JSON content
• Sort keys alphabetically
• Works with JSONP responses
• Handles numbers larger than Number.MAX_VALUE
• Customizable tab size, themes, and CSS
• Omnibox integration: type "json-viewer" in the address bar to format JSON or open a scratch pad
• Configurable max file size for highlighting

The extension only activates when it detects JSON content. It does not collect any data.
