JSON Javascript highlighting in Visual Studio 2010
Tools -> Options -> Text Editor -> File Extension
End your extension 'json' and select 'Script Editor' and click 'add'.
Re-open any json documents for it to take affect.
Another option is to use Text Highlighter (extention for Visual Studio 2010), which offers syntax highlighting for the following text formats:
- .json (also offer syntax validation)
- .bat
- .cmd
- .ini
- .txt
- .log
Great news!
