Getting an array from 1 to number of columns from csv output

[zillurbmb51]

One of my process gives output of one csv file. I want to create an array channel from 1 to number of columns. For example:
My output

my_out_ch.view() -> test.csv

Assume, test.csv has 11 columns. Now I want to create a channel which gives me:

1,2,3,4,5,6,7,8,910,11

How could I get this? I have tried with splitText operator as below without luck:

my_out_ch.splitText(by:1,limit:1)

But it only gives me the columns names. There is a parameter elem, I am not sure if elem could give me the array and also not sure how to use it. Any help?

Try:

my_out_ch.splitCsv(skip:1)
