Simple Xls to Html Converter

gistfile1.rb

# To use this application, you need to install the following and specify RubyGem
# >> sudo gem install roo -v 1.3.11

# Which should return something like
# >> Successfully installed ruby-ole-1.2.10.1
# >> Successfully installed spreadsheet-0.6.4.1
# >> Successfully installed GData-0.0.4
# >> Successfully installed roo-1.3.11
# >> 4 gems installed

# So here we have our basic class

require "rubygems"
require "roo"

class SimpleXls2HtmlConverter
  def initialize(file = "", default_sheet = 0)
    @spreadsheet = Excel.new(file)
    @spreadsheet.default_sheet = @spreadsheet.sheets[default_sheet]
  end
  
  def converts_column(column_name = "A")
    lines_converted = []

    (@spreadsheet.first_row).upto(@spreadsheet.last_row) do |line|
      lines_converted << @spreadsheet.cell(column_name, line).to_s.gsub("\n", "<br/>")
    end

    lines_converted
  end

  def object
    @spreadsheet
  end
end

# And here the implementation of this class

spreadsheet = SimpleXls2HtmlConverter.new("base.xls")
puts spreadsheet.object.info
puts spreadsheet.converts_column
puts spreadsheet.converts_column("B")
puts spreadsheet.converts_column("C")
