It is possible to get an excel column name to set a case value?
Not a best way to show you my expectation than with an example.
Example
Input excel file
LastName,FirstName,Maths,IT
John,Polo,10,15
Mike,Dupond,6,9
Result excepted
LastName,FirstName,Course,Grade
John,Polo,Maths,10
John,Polo,IT,15
Mike,Dupond,Maths,6
Mike,Dupond,IT,9
Here my actual Talend structure
Currently, this structure allow me to obtain this result:
LastName,FirstName,Course,Grade
John,Polo,"",10
John,Polo,"",15
Mike,Dupond,"",6
Mike,Dupond,"",9
Thank's for help!
