Hey @afna if i’m not wrong your are reading some excel file then save in the dt (datatable ) variable now you are doing the iteration to read all the values from the multiple column and store the columns data in multiple assign .
so you can use for each row activity inside the for each use assign activity on the required num of columns data you want - like 3,5
so inside the for each loop drag 1 assign activity
in the left hand side create the variable and in the right side use currentrow(“yourcolname”).tostring
that way you can store the datas
cheers
