Excel functionality for contact, donate, etc

• Create Excel functionality so that whoever updates the website can update the excel and generate a link

[hansbala]

On some brief research, we can go two ways:

• Handle the Excel updating logic over the website (this will probably include sending a POST request to the server and handle those responses there which will require restructuring the server to use Node.js Express instead of ngnix, if noone here is familiar with how to handle POST requests in ngnix)
• Or, we could use the Google Sheets API (this seems simple and the Google Sheets link will get updated in real-time. Honestly, this seems like the easier route (however, I kinda question the security aspect of this). If someone gets, access to the sheets link they could potentially edit the file unless we secure the sheet behind an API key and restrict visibility to some team members.

The latter gets my +1 vote as it requires much much less restructuring, and if I get time, will implement it in the coming days!
