See it's git repo for the detail on how to install and run.

If you want the green screen shown in the instructions edit the config.ini in .crypto directory which is created after you first run the app. Change the default values to the following.

Get Hyperlink Value From An Excel Cell

August 3, 2017

I received a spreadsheet with a list of addresses setup so you can click the name in the cell and it would open. I wanted to export the actual url which is inside the cell.

You can do this with a function. Open the VBA editor with Fn/Option F11 on the Mac. Then Open Modules and insert a new module with a name of your choosing.

Paste in the following function, save and exit the VBA editor

Function GetCellURL(cell As Range) As String
     On Error Resume Next
     GetCellURL = cell.Hyperlinks(1).Address
End Function
