One of our customers shared with us the challenge they were having with a large workbook created by an external reporting system. Excel was very sluggish as they were working to analyze the data. They decided to use WBmerge to create a new copy of the workbook. The end result was a new workbook 75% smaller and very responsive in Excel.
We never thought of using WBmerge for this task, but we are glad our customer shared this story with us.
