If I then created a pivot table on a second sheet from this data, but don’t explode it (i.e. When I saved the workbook, I got a file size of 50 MB. one million rows per column) of =rand() then converted them to values. On my home pc, using excel 2007 I create d 3 complete columns (i.e. On the bloat that a pivot table adds, I posted a comment over at recently that illustrates this. Unfortunately the whole process is a bit complicated to explain here, but perhaps will make a good future post subject. Then when you choose the particular column you want, you just need to add the keyword ‘Distinct’ after the ‘Select’ keyword in the SQL query that Microsoft Query builds for you.
