That runs in a couple of seconds here. There must be something else making
it a lot slower. Splitting the sheets out with ParseExcel takes about a
minute, so just having about four hundred worksheets may account for
a good chunk of the time if there is substantial per sheet overhead.
There also is a query per sheet that takes about a quarter of a second per
sheet. This would account for about a minute and a half right there.
