Spreadsheet::ParseExcel - Get information from an Excel file.
============
Version: 0.5.0
Date: 2006-04-24

Short Description:
Spreadsheet::ParseExcel allows you to get information out of a
simple Excel file
This Package is an - as of today incomplete - translation of
Kawai Takanoris Perl-Module.


Requirements
------------

* ruby 1.8

Install
-------

De-Compress archive and enter its top directory.
Then type:

$ ruby setup.rb config
$ ruby setup.rb setup
($ su)
# ruby setup.rb install

You can also install files into your favorite directory
by supplying setup.rb some options. Try "ruby setup.rb --help".


Usage
-----
#!/usr/bin/env ruby

require 'parseexcel/parser'

# 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|
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)
