@Brian Wells Thank you, your suggestion did the trick, but not totally... Worked for the mixed field int-string, but the datetime columns went with strange characters after that, so i applied a "hack" over the "hack".

1.- Do a System.Io.File.Copy and create a copy of the excel file.

2.- Modify the Datetime column headers programatically at runtime to something in datetime format, i.e. "01/01/0001".

3.- Save the excel, and then apply your trick doing the query with HDR=NO to the modified file.

Tricky, yes, but worked, and reasonabily fast, if anyone has any alternative to this, i will be glad to hear.

Greetings.

P.D. Excuse my english, it isn't my native language.
