Hello everyone,

I currently have code that uploads a csv and processes the data and saves to a database. I'm looking to enhance this upload tool with the following features:

• Preview file and use drop down menus to map columns to database columns (I have this UI generating).
• Pass the whole file and the selected columns back to the server (I am stuck here.)

Feel free to ask for more explenation. I appreciate any help that anyone can provide here.
