Hi, I'm Robert and I'll be helping you with your computer question.
its pretty easy to do
just run the report and the click export / to excel / new workbook
that exports a file that will no longer have any connection to quickbooks but will be a stand alone excel file. You can do anything you want to it within excel and it will have no effect on quickbooks.
This page not only shows how to do it but it gives some advanced tips to make it more readable in excel if you choose to use them
