I'm having trouble importing an excel CSV document into SAS 9.4. (~2 million rows, should only be 60 variables upon import, but it >250 variables) The first thousand or so lines look good, but eventually SAS is reading in multiple observation lines and putting them into one line creating hundreds of extra variables. Here is the code I've used to import it.    libname CDC "filepath";   PROC IMPORT OUT= cdc.filename DATAFILE= "filepath\file.csv" out=Q12018 dbms=csv replace; delimiter=',';guessingrows=max; getnames=no ; RUN;     For example instead of data looking like this: ID        visit number      name        0           012                 joe 1          123                   jane 2           234                  john   It looks like this (after several thousand rows): ID      visit number     name     var4     var5      var6 0          012                 joe 1        123                  jane       2           234        john   Any help is appreciated! Thanks!   ... View more
