Aww heck, I decided to write it up anyhow. You can download the code here ...
http://amazecreations.com/datafast/D...tfromexcel.zip
and the bulk of the logic is posted below. You'll need a table to map the columns
from Excel to Access. The code below is looking for one called ImportColumnSpecs.
The download doesn't have a form to launch it, so you'll have to run from the debug
window with a command like this ...
ProcessFileImport "C:\download\sales.xls","sales_import"
Good Luck

I've been doing a lot of importing from Excel lately, and have noticed that
it is the rare spreadsheet that imports cleanly. I've gone to using automation
to loop through rows and insert into a table myself. Are you interested in
this solution? If so, I'll post the code, but it's not a trivial solution and will
require tweaking for each spreadsheet you plan to import.
If you post back, I'll try to clean up the code and post it here.
