I am working on an inherited workbook (.xlsb not sure is that matters here or not) that is very large for the small amount of data/reports in it. I discovered that the UsedRange for two of the worksheets is a column only reference: $A:$AU. Hence, 1M+ rows being stored with no data.
I have tried numerous examples on how to "reset" the UsedRange, but none of have worked. There are now Named Ranges or Formulas that have entire column references, no filters to the entire column and no formatting.
Even when I deleted columns A:AU but the UsedRange remains a columns only reference.
Any suggestions would be greatly appreciated.
