tJavaRow component code for Excel

EnriqueLDE — Mon, 11 Feb 2019 09:47:28 GMT

Hello,

I'm trying to read some columns from my Excel file using tJavaRow component but I don't know the code to do this.

Designer:

tFileInputExcel -> tJavaRow -> tFileOutputExcel

I ask it because later I will continue doing more stuff using this component, but I won't be able to do this if I don't read those columns first.

Thanks!

@fdenis I use tFileInputExcel to read those columns but i want to use tJavaRow later to work with those columns using code. The problem is I don't know the reference i need to use in Java to start programming. For example, what is the code to refer to colum 1?

Thanks!

you have to use org.apache.poi components and file Output stream.
it's not so complex but it's code not visual programming...
ETL jobs have to be easy to read… so prefer to use components if you can.

Talend use apache.poi so you can have a look on code tab when you are using tFileInputExcel… for examples.
