JsonViewer

IMPORTANT!!! Setup content type and opera config as described in sections [MIME Type] and [Opera:config]. Otherwise extension may not work. Extension formats and highlights JSON data loaded from file or server String and boolean values are highlighted with blue, numbers - with green, null values - with red color. [MIME Type] Note: if server returns content type "application/json" for JSON data then Opera will prompt to download JSON file because Opera doesn't know such content type. To make it displayed by Opera instead of downloading it: 1. Go to Opera preferences -> Advanced -> Downloads. 2. Press Add button (if you haven't added content type "application/json" previously. Otherwise just edit it and go to item 4). 3. Enter MIME type "application/json" (without quotes) and file extension "json" (also without quotes). 4. Select action "Open with Opera". 5. Press Ok buttons to apply your changes. You can use http://ratesby.appspot.com/values page to test this extension [Opera:config] Ensure that options opera:config#UserPrefs|UserJavaScript and opera:config#UserPrefs|AlwaysLoadUserJavaScript are enabled. If they aren't then extension will not work
