Anyone here can Help & Explain in detail how to input csv data in forms

[spa3212]

I am totally fed up and could not find a proper way of inputting data from a CSV file into a web form.

I have csv like this

I want to input data of Col A into Field one
input data of Col b into 2nd field
and col C data into 3rd field
it will input col,a,b,c data in three field of a form.
and will move to row no. 2 and do the same.

Also is there any way, I can specify from which col and row data is to be pick. Like If I want to start picking data from 3rd row of each column
or from col B only..I means we can specify the from where to pick the data.

please assume I am very new and just learning your help is much appreciated.

Edit, if I use parse line ,
it split one cell like E as username variable
and rest as password variable, I think coz it assume : as separator..
