Hi all,
SAS 9.4
I 'm trying to create a loop so that all the xlsx-files are imported. I notice that the code below is wrong but I don't know how to correct it the right way. I have 4 excelfiles to import. The result of this code is that the first excelfile is imported 4 times (and it overwrites itself each time). The result should be that 4 each excel file is imported once. Each excelfile has a different variable in its filename (ERK = 009, 090,091,777). Only the 009 is imported. Could anyone help me with this please?
/*macro to import a single excel*/
%macro import(input);
OPTIONS VALIDVARNAME=ANY;
PROC IMPORT OUT=work.B1B2_E&erk. (keep = N_BUD_AN ID_AGR TIT_N Source N2018)
DATAFILE= "&path\&input..xlsx"
DBMS=excelcs REPLACE;
RANGE="B1B2$"; /*to import the sheet completely*/
SCANTEXT=YES;
USEDATE=YES;
SCANTIME=YES;
RUN;
%mend;
/*loop to import all the files*/
%macro Loadall;
%do i=1 %to &numobs;
%import(&&filein&i);
%end;
%mend;
%loadall;
Since you do not change &erk in the loop (or derive it somehow from &input), the dataset is always overwritten with the data from the latest import.
How do I write the code?
Before the macro this is written.
/*Each Excel file gets a variable, number*/
data _null_;
set mydata.deelnemerslijst end=endobs;/*end=variable --> at the last observation it starts counting*/
call symputx('fileIN'!!left(_n_),excel_file);/*takes the name and puts a number in front "n" (_n_ counts the lines --> this combination is named 'fileIN'*/
if endobs=1 then call symputx('numobs',_N_);
run;
You need to make up a rule for building the macro variable erk.
