I think you can use the 2010 ACE OLE DB driver to read from 2007 workbooks. It's possible you'd have to change the Excel version in the connection string.
To read Excel 2007 (.xlsx files), I believe you need this as the first two arguments to OPENROWSET:
SELECT *
FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
'Excel 12.0;HDR=NO;Database=filename.xlsx,'SELECT * FROM [Sheet1$]')
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
