Excel Web Add In - Launch FileOpenDialog and access Desktop application API RRS feed

  • Question

  • Hi there,

    I have searched the web and came to a conclusion that I can not open up an external application's file ( that is installed on my machine.

    To open up a file, I need FileOpenDialog (or some other UI where user will be able to navigation to that file say and select that to provide the file path). Once the file is selected, I like to use the external application API to interact with that file and get the information from that file/application into the Excel. It seems like this is not possible from Web Add In?

    I really hope that that conclusion is incorrect and there IS a way to access a local file and use external API to work with from the Web Add In.

    If Web Add In is not the right way, is there any other way that I can create an Add In to excel that could interact with desktop directly. (My knowledge to c or cpp is almost none.)

  • Hi Musa,

    In advance, I'm not sure if I can understand what you want.
    I suppose you mean "file association" or an application associated with a file extension. It depends on PCs, different PCs have different file association.
    If you want to know what application is associated with a specific file extension, you can find it in registry.
