Souga, the problem is that SAS uses the Excel Jet engine and checks the
first 8 rows to determine the data type of an Excel column when creating
a SAS variable from it. If it finds only characters, then it becomes
character variable; if it finds mixed numbers and characters, it becomes
a character variable; if it finds only numerics, then it becomes a
numeric variable---AND: any character values in rows 9 - infinity become
missing values. Argh! Sound familiar?!?!?
This problem and the workaround are covered in fellow Westatian Ed
Heaton's very popular, award-winning SUGI 31 paper:
So, Your Data Are in Excel!
The workaround is not for the faint of heart, as it calls for modifying
something in the Windows registry. But, you strike me as a bold person,
so check it out!
Souga, best of luck to you in resolving your Excel data issues!
I hope that this suggestion proves helpful now, and in the future!
