Basically, the way it would ideally perform is the equivalent of a VLOOKUP as it would have to match the activeUser e-mail and then retrieve and store the value from the corresponding column.
The data would be stored in the following way:
col1, row1: firstname.lastname@example.org col2, row1: 90% col3, row1: 1
And the desirable result would be the script importing c1;r1 if c3;r2 contains 1. (This would have to work by matching the e-mail of the current user in the website and then find the column/row where it contains his data)
