How to use CSVTranslator in workflow to trnasform an inout file to Data

[ssukhija]

Hi 

I am trying to implement a price uplift workflow where each price uplift has a cieling of Product Catalog Product Price, so customer is never paying more than the current Product price. The Pricing information is available in a file, which I am addign as input. I would like to access data from this file, without adding too many iterations/queries. I think csvtranslator is the bext method to do so, I can transform the file and later use data in subsequent steps. Does anyone have  examples or documentation on how to do it.
