Usage

#!/usr/bin/env ruby

require 'parseexcel'

your first step is always reading in the file.

that gives you a workbook-object, which has one or more worksheets,

just like in Excel you have the possibility of multiple worksheets.

workbook = Spreadsheet::ParseExcel.parse(path_to_file)

usually, you want the first worksheet:

worksheet = workbook.worksheet(0)

now you can either iterate over all rows, skipping the first number of

rows (in case you know they just contain column headers)

skip = 2 worksheet.each(skip) { |row|

a row is actually just an Array of Cells..

first_cell = row.at(0)

# how you get data out of the cell depends on what datatype you
# expect:

# if you expect a String, you can pass an encoding and (iconv
# required) the content of the cell will be converted.
str = row.at(1).to_s('latin1')

# if you expect a Float:
float = row.at(2).to_f

# if you expect an Integer:
int = row.at(3).to_i

# if you expect a Date:
date = row.at(4).date

# ParseExcel makes a guess at what Datatype a cell has. At the moment,
    # possible values are: :date, :numeric, :text
    celltype = first_cell.type

}

if you know exactly which row your data resides in, you may just

retrieve that row, which is again simply an Array of Cells

row = worksheet.row(26)
