Answer 1

I know this is an old question, but Bhanu Pratap's code from Daniel Khan required updating before I could use it in Office 365. That code was written for a 32-bit Excel environment, but the modern Excel uses a 64-bit environment and returns errors on his code. I almost thought I would not be able to salvage his code! Since I finally found out how to make it work, I wanted to post it here in-case anyone else also finds it useful.

Excel 64-bit Code:
