# Run the following if you haven't done so before:
gem sources -a http://gems.github.com/

# Install the gem:
sudo gem install roo

require 'rubygems'
require 'roo'

s = Openoffice.new("myspreadsheet.ods")      # creates an Openoffice Spreadsheet instance
s = Excel.new("myspreadsheet.xls")           # creates an Excel Spreadsheet instance
s = Google.new("myspreadsheetkey_at_google") # creates an Google Spreadsheet instance
s = Excelx.new("myspreadsheet.xlsx")         # creates an Excel Spreadsheet instance for Excel .xlsx files

s.default_sheet = s.sheets.first  # first sheet in the spreadsheet file will be used

# s.sheet is an array which holds the names of the sheets within
# a spreadsheet.
# you can also write
# s.default_sheet = s.sheets[3] or
# s.default_sheet = 'Sheet 3'

s.cell(1,1)                                 # returns the content of the first row/first cell in the sheet

s.cell(1,'A',s.sheets[0])                   # same cell

# almost all methods have an optional argument 'sheet'.
# If this parameter is omitted, the default_sheet will be used.
