Using fields as headers

[Anonymous]

Hello,

I have a situation that I can't imagine how to solve using Talend Studio. Yes, I'm a beginner (sorry if the problem has an obvious solution but I can't find it.

I have a file like this:

CAMPO1  CAMPO2  CAMPO3  CAMPO4
C1Valor1  C2Valor1  C3Valor1  C4Valor1
C1Valor1  C2Valor1  C3Valor2  C4Valor2
C1Valor1  C2Valor2  C3Valor1  C4Valor3
C1Valor1  C2Valor2  C3Valor2  C4Valor4
C1Valor2  C2Valor3  C3Valor1  C4Valor5
C1Valor2  C2Valor3  C3Valor2  C4Valor6
C1Valor2  C2Valor3  C3Valor3  C4Valor7

C1ValorN  C2ValorN  C3ValorN  C4ValorN

I need an excel output whith this structure:

C1Valor1
	C2Valor1	C2Valor2	C2Valor3
C3Valor1	C4Valor1	C4Valor2
C3Valor2	C4Valor3	C4Valor4
C3Valor3	C4Valor5	C4Valor6	C4Valor7
C1ValorN
	C2ValorN
C3ValorN	C4valorN

I can't find nothing specific to do this in Talend. 

Could someone give me clues about it.

Can you give some details regarding the transformation rules to be applied?

There are no tranformations, the fields in the CAMPO2 of the original must be change to headers of the exit. 

You have to distribute all the values from CAMPO4 maching the conditions of the fields in CAMPO2 and CAMPO3 and grouping everything by the value of CAMPO1.
