Click a phone number in a spreadsheet to ring?
I use MS Excel 2013 at work for various client contact databases. I use Dropbox so that I can access the data from anywhere using a PC, iPad, or iPhone. I would like to be able to use my iPhone 5 to open the spreadsheet (in ? app ...), click on the client's number & have the iPhone activate & ring that number for me. I don't want to add the clients to my iPhone Contacts. I want to work directly from the Spreadsheet. Can anyone think of a way that this could be done using Formulas, Cloud Storage, Apps? Thank-you in advance for any thoughts, solutions you can come up with. I'm this would be useful for lots of people, too.
