Deleting empty rows

Hi,

I am importing excel into SAS. The excle sheet has 181 rows (first row for variables' names) but I get 189 rows when importing to SAS, this means I have 8 empty rows (see below). I see that the Excel sheet goes to 189 (meaning it seems formatted this way). Here is the Code I am using:

 

PROC IMPORT OUT= WORK.dataset DATAFILE= "C:\proj.xlsx"
DBMS=xlsx REPLACE;
GETNAMES=YES;
RUN;

 

How can I tell SAS to import only the rows with valid observations?

 

SAS Output

180 180 0 20 158 1 0 0 1
181 . . . . . . . .
182 . . . . . . . .
183 . . . . . . . .
184 . . . . . . . .
185 . . . . . . . .
186 . . . . . . . .
187 . . . . . . . .
188 . . . . . . . .
189 . . . . . . . .

Are all of the fields numeric, character or a mixture of both?

Re: Deleting empty rows

I'm not aware of a way to do it during import but, regardless of whether you have numeric variables, character variables, or a mixture of both, the following should work after you've imported the file:

 

data have;
  input a b $ c d $ e f $ g;
  cards;
1 2 3 4 5 6 6
1 . 3 4 5 6 7
1 2 . 4 5 6 7
. . . . . . .
. . . . . . .
. . . . . . .
;
data want;
  set have;
  if not (nmiss(of a--g) eq 7);
run;

Re: Deleting empty rows

Thank you both for your replies. I am sorry, I am not familiar with these commands. Can you please modify them for the purpose of my code? What does

if not (Cmiss(of a--g) eq 7);

 Cmiss or Nmiss mean? and a--g or eq 7??

CMISS() is for both numeric and characher variable,

while NMISS() is only for numeric variable.

The following code worked just fine:

 

data try;
set new;
if cmiss(of _all_) then delete;
run;

 

Thanks!

I agree that cmiss would be more appropriate but, in this case, both cmiss and nmiss provide the same result.

Simple and effective. I've now saved this in my codes folder. Thank you very much!

Be prepared if using Proc Import and Excel files that the exact same cause for you "blank" rows will also create "blank" variables. The issue here is that Excel will consider any row or column that had any value entered into any cell init, even if deleted, as "active". The engine that SAS talks to with Excel via Proc Import is told by Excel that the cells should have values.

 

You will at some time likely get varaibles named VARxx with no data.

In excel select rows 181-189.  Delete them.  Save the excel file.  Excel now thinks the end-of-sheet is row 180..  Re-import.
