Question

I am trying to open a spreadsheet stored remotely using the Ruby Spreadsheet gem. My code is as follows

require 'spreadsheet'
require 'open-uri'

book = Spreadsheet.open(url)

It is returning me an error of Errno::ENOENT: No such file or directory

By putting the url into the browser, it downloads fine, so I know the url is fine. I have some very similar code using FasterCSV which works absolutely fine, so wandering if this is an issue with Spreadsheet, or I’m doing something wrong.

Answer 1

You’re not using open-uri, which will fetch the URL and expose it as a StringIO object (which works like an IO object in most cases). The Spreadsheet class may work if you do this instead:

book = Spreadsheet.open(open(url))

The second open is from OpenURI which will send the StringIO object to Spreadsheet.open.
