Is there K2 service/process that can be used to read an attachment file into a grid/table? I know this can be done in asp.net but I am looking for a way to do it with K2. The attachment file would be a csv or excel which ever is easiest for K2 to read. I want to some how do a bulk entry into a smartobject and then do validations on the entires. Can this be done using a workflow?
