unable to perform actions on data loaded

[papyr]

Hi,
I am trying to use your tool to import some data into my tables using ASP MVC

When I wanted to try one our your samples to load an external file to load TAB separated data, and apply some actions (Filter some cols, aggregate others) then map -> the columns to my columns inside my database table, I could not get it to work.

Can you outline the steps and show me a sample on how to do so.

Can we use pure JS/jquery or Razor partial views

thanks
