The "WHY" in a bit more detail than @ChrisNZ mentions is that if a column or row in Excel has a value entered in a cell and then the value is deleted Excel "remembers" the column or row has been used. So when you ask Excel to tell you what is in the data via Proc Import it tells the data linkage that column has data.
You might also want to check for entire rows at the end of your data set without values.

@ballardw that was a very good explanation. I just created new excel sheet and no issues so far. Even i was having blank columns while importing because i highlight whole row.
After creating new excel , everything is okay.
many thanks for explaining WHY?
