I inherited a new process and a spreadsheet that belongs in a beginner Excel class. The main issue I have right now is that I have about 8k rows of data, the data is not grouped, and a person in my distribution list runs a macro on it for whatever need they have. He mentioned changing the coding, so I'm assuming he's built it in VBA. I'd like to be able to group this data, so I can print a single page summary report without having to juggle the same file in different formats. Is grouping the data going to disrupt his macro without additional coding?
