Problem with parsing excel file using spreadsheet

Rails
1

Hi,

I am using ruby ruby 1.8.6 and spreadsheet (0.6.4).
I am trying to oarse an excel file.
My code is like :

require 'rubygems'
require 'spreadsheet'
require 'parseexcel'
equire 'parseexcel/parseexcel'
require 'parseexcel/parser'

  workbook =

Spreadsheet::ParseExcel.parse(“public/downloads/test.xls”)
worksheet = workbook.worksheet(0)

    worksheet.each { |row|
            puts row.at(0).to_s

    }

But it prints ‘nil’. I have data in my excel file.

Could you please help me?

Thanks,
Anu
