Here is the structure of the file :
id|country_code|Country_name
1,2,3|cm,fr,us|Cameroon,France,United States

We want to transform it to something like :
id|country_code|Country_name
1|cm|Cameroon

Re: transpose a file: invert rows in columns

you can achieve this with help of tnormalizerow and numeric sequence routine.

using tnormalizerow and sequence routine  you will have to generate following 

id seq  country code seq      country_name seq

1  1       cm                  1         cameroon        1

2  2       fr                     2         france              2

3  3        fr                     3         united states   3

 

after this you can perform join operation on seq column 

and you will get

 id|country_code|Country_name
1|cm|Cameroon
2|fr|France
3|us|United States

 

This is applicable for n number of records
