    Retrieving a file is not the responsibility of your spreadsheet gem, but there are a number of ways to get things like that. The easiest is to use open-uri, and the most robust is to use the curb gem which is a wrapper around libcurl.

    Simple example:

    require 'open-uri'
    
    spreadsheet = open('https://example.com/spreadsheet.xls').read
    

    The curb gem has a pile of additional options that make this statement more tolerant of bad network connections and invalid SSL certificates, among other things. It can also be used to POST back a modified spreadsheet if that’s a requirement.
