Loading Table in a Crosstable / Transposed way

I am looking for a way to load data that has many columns that keep changing.  For Example the first 2 columns would be the qualifier fields and all columns after that would be an attribute:  example from

to having it like this 

It is possible to create with an excel file reader and an Alter format step, but the columns will be different in the next file and if no Oranges were taken that column will not be in the file so the job will fail.  Also the actual number of ever changing columns can be anything from 20 to 400 - so setting your qualifier fields and automatically adding anything that comes after that as an Attribute field seems like the solution I need.

Anyone have any ideas?

Hi Mel!

Yes if it's backed by a database - just use the pivot function. But if it's Excel, we read stuff schema first. So you’d be best to do the transpose in Excel (or as part of the ETL).

Thank you mariae059, it is indeed Excel files, about 150 files per month all of them with different columns - I am currently handling the transpose outside of Ataccama but was really hoping for a way to do it in the product - who knows maybe they will give us this functionality in the future.
