I know there are 2 similar questions. I have a very large Excel file separated in sections by 3 blanks lines. I was wondering if there was a way to split the spreadsheet into other every time there is a blank in column A or every time the word "Section" appears in column A.
I recommend reading the posting Split Worksheet, Seperated By Blank Rows, Into Several Worksheets and tailoring it to fit your needs.
