How to chop a long Excel cell string

Mirisage — Sat, 09 Jun 2012 23:43:28 GMT

Hi Colleagues,

I was given the names of over 200 variables just as a single Excel string (attached).

I want to separate individual variable names as:

AA_VAR1

AA_VAR2

AA_VAR3

AA_VAR4

I separated them using text function of Excel like below but it took me the time almost same as doing manually.

=LEFT(B2,7)

=MID(B2,9,7)

=MID(B2,17,7)

I wonder if there is an automated way of doing using SAS?

Any help is appreciated.

If you ultimately want to bring these names back in Excel, the simplest thing to do is to use the Data-Conversion operation with spaces as delimiters directly in Excel. You'll get your 241 variable names in the first row which you may then paste-transpose to get a single column.

If you insist on doing this operation in SAS, then look at the SCAN function. As in :

data want;

set have;

do i=1 by 1 until(missing(name));

name = scan(names, i);

if not missing(name) then output;

end;

drop names;

run;

Hi PG,

Many thanks.

I have just taken a piece of that string to try your SAS code. I cannot figure out why it doesn't work. Time permitting, I wonder if you could help again.

data have;

input names $250.;

cards;

AA_VAR1 AA_VAR2 AA_VAR3 AA_VAR4 AA_VAR5 AA_VAR6 AA_VAR7 AA_VAR8 AA_VAR11 AA_VAR12;

run;

data want;

set have;

do i=1 by 1 until(missing(name));

name = scan(names, i);

if not missing(name) then output;

end;

drop names;

run;

There were minor problems, corrected now:

data have;

length names $250;

input names & ;

cards;

AA_VAR1 AA_VAR2 AA_VAR3 AA_VAR4 AA_VAR5 AA_VAR6 AA_VAR7 AA_VAR8 AA_VAR11 AA_VAR12

;

data want;

length name $8;

set have;

do i=1 by 1 until(missing(name));

name = scan(names, i);

if not missing(name) then output;

end;

drop names;

run;

Hi PG,

A big thank for you. This is great! Worked well! Now I came to know about scan function too.
