How to get spreadsheet data to the server

Spreadsheet
#1

I’ve gone through the documentation and many items in this forum topic but cannot find the answer. To get data from the web server to the form, I can use JSON. How do I get the information back to the server to process and save the changes? Am I using a FORM POST? Do I need to use Ajax or sockets? I can’t find anything that explains sending the data back to the server for processing.

Can anyone please point me to the correct documentation or post topic to show this?

Pretty please.
