Synopsis

Axlsx is an Office Open XML Spreadsheet generator for the Ruby programming language. With Axlsx you can create excel worksheets with charts, images (with links), automated and fixed column widths, customized styles, functions, tables, conditional formatting, print options, comments, merged cells, auto filters, file and stream serialization as well as full schema validation. Axlsx excels at helping you generate beautiful Office Open XML Spreadsheet documents without having to understand the entire ECMA specification.

Feature List

Author xlsx documents: Caxlsx is made to let you easily and quickly generate professional xlsx based reports that can be validated before serialization.
Generate 3D Pie, Line, Scatter and Bar Charts: With Caxlsx chart generation and management is as easy as a few lines of code. You can build charts based off data in your worksheet or generate charts without any data in your sheet at all. Customize gridlines, label rotation and series colors as well.
Custom Styles: With guaranteed document validity, you can style borders, alignment, fills, fonts, and number formats in a single line of code. Those styles can be applied to an entire row, or a single cell anywhere in your workbook.
Automatic type support: Caxlsx will automatically determine the type of data you are generating. In this release Float, Integer, String, Date, Time and Boolean types are automatically identified and serialized to your spreadsheet.
Automatic and fixed column widths: Caxlsx will automatically determine the appropriate width for your columns based on the content in the worksheet, or use any value you specify for the really funky stuff.
Support for automatically formatted 1904 and 1900 epochs configurable in the workbook.
Add jpg, gif and png images to worksheets with hyperlinks
Reference cells in your worksheet with "A1" and "A1:D4" style references or from the workbook using "Sheet1!A3:B4" style references
Cell level style overrides for default and customized style objects
Support for formulas, merging, row and column outlining as well as cell level input data validation.
Auto filtering tables with worksheet.auto_filter as well as support for Tables
Export using shared strings or inline strings so we can inter-op with iWork Numbers (sans charts for now).
Output to file or StringIO
Support for page margins and print options
Support for password and non password based sheet protection.
First stage interoperability support for GoogleDocs, LibreOffice, and Numbers
Support for defined names, which gives you repeated header rows for printing.
Data labels for charts as well as series color customization.
Support for sheet headers and footers
Pivot Tables
Page Breaks

gem 'caxlsx'

Usage

Here's a teaser that kicks about 2% of what the gem can do.

Axlsx::Package.new do |p|
  p.workbook.add_worksheet(:name => "Pie Chart") do |sheet|
    sheet.add_row ["Simple Pie Chart"]
    %w(first second third).each { |label| sheet.add_row [label, rand(24)+1] }
    sheet.add_chart(Axlsx::Pie3DChart, :start_at => [0,5], :end_at => [10, 20], :title => "example 3: Pie Chart") do |chart|
      chart.add_series :data => sheet["B2:B4"], :labels => sheet["A2:A4"],  :colors => ['FF0000', '00FF00', '0000FF']
    end
  end
  p.serialize('simple.xlsx')
end

Please see the examples folder for further information on what you can do with this gem Chances are that it has already been implemented. If it hasn't, let's take a look at adding it in.

Plugins, Integrations, and Extensions

Currently the following additional gems are available:

acts_as_caxlsx
- Provides simple ActiveRecord integration
caxlsx_rails
- Provides a .axlsx renderer to Rails so you can move all your spreadsheet code from your controller into view files.
activeadmin-caxlsx
- An Active Admin plugin that includes DSL to create downloadable reports.
axlsx_styler
- Allows you to build clean and maintainable styles for your axlsx spreadsheets. Build your spreadsheeet with data and then apply styles later.

Known Software Interoperability Issues

As axslx implements the Office Open XML (ECMA-376 spec) much of the functionality is interoperable with other spreadsheet software. Below is a listing of some known issues.

Libre Office
- You must specify colors for your series. see examples/chart_colors.rb for an example.
- You must use data in your sheet for charts. You cannot use hard coded values.
- Chart axis and gridlines do not render. I have a feeling this is related to themes, which axlsx does not implement at this time.
Google Docs
- Images are known to not work with google docs
- border colors do not work
Apple Numbers
- charts do not render
- you must set 'use_shared_strings' to true. This is most conveniently done just before rendering by calling Package.use_shared_strings = true prior to serialization.

p = Axlsx::Package.new
p.workbook.add_worksheet(:name => "Basic Worksheet") do |sheet|
  sheet.add_row ["First Column", "Second", "Third"]
  sheet.add_row [1, 2, 3]
end
p.use_shared_strings = true
p.serialize('simple.xlsx')
