I'm no longer maintaining this code. It's under active development here and new releases should be coming from that repository:
https://github.com/Empact/roo
Roo is available here and on Rubyforge. You can install the official release with 'gem install roo' or refer to the installation instructions below for the latest development gem.
Homepage: https://roo.rubyforge.org/
Gemcutter: https://rubygems.org/gems/roo
# Run the following if you haven't done so before:
gem sources -a https://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('A',1) # same cell
s.cell(1,'A') # same cell
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.
s.info # prints infos about the spreadsheet file
s.first_row # the number of the first row
s.last_row # the number of the last row
s.first_column # the number of the first column
s.last_column # the number of the last column
# limited font information is available
s.font(1,1).bold?
s.font(1,1).italic?
s.font(1,1).underline?
