Create SQL INSERT from Excel file (ruby script)

import excel file into SQL.
first row is column names.

require 'win32ole'
xl = WIN32OLE.connect('Excel.Application')
wb = xl.ActiveWorkbook
wb.Worksheets.each do |ws|
    data = ws.UsedRange.Value
    if data!=nil
            field_names = data.shift
            flds=field_names.join(',')
            data.each do |row|
                row.collect! { |f| f = "'" + f.to_s + "'" }
                puts ("INSERT INTO [#{ws.Name}] (#{flds}) VALUES \
                    ( #{row.join(',')} );")

            end
  end
end
