Weight Converter

The weight variables for the Online and Windows versions of the DAS differ. The Weight Converter will replace Windows weight variables in TPFs/CPFs with Online weight variables. You can submit one TPF/CPF individually or many compressed into a zip file. Files must be .TPF, .CPF, or .ZIP. Once the weight variables are changed, you can submit the new zip file to the Batch Processor.

NOTE: The Weight Converter works only with datasets available in the Online format.
