Synopsis

Axlsx is an Office Open XML Spreadsheet generator for the Ruby programming language. With Axlsx you can create excel worksheets with charts, images, automated column width, customizable styles, functins, merged cells and auto filters 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.

There are guides for using axlsx and acts_as_xlsx here: http://axlsx.blogspot.com

Help Wanted

I'd really like to get rid of the depenency on RMagick in this gem. RMagic is being used to calculate the column widths in a worksheet based on the content the user specified. If there happens to be anyone out there with the background and c skills to write an extenstion that can determine the width of a single character rendered with a specific font at a specific font size please give me a shout.

Feature List

**1. Author xlsx documents: Axlsx is made to let you easily and quickly generate profesional xlsx based reports that can be validated before serialiation.

**2. Generate 3D Pie, Line and Bar Charts: With Axlsx 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.

**3. 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.

**4. Automatic type support: Axlsx will automatically determine the type of data you are generating. In this release Float, Integer, String and Time types are automatically identified and serialized to your spreadsheet.

**5. Automatic column widths: Axlsx will automatically determine the appropriate width for your columns based on the content in the worksheet.

**6. Support for automatically formatted 1904 and 1900 epocs configurable in the workbook.

**7. Add jpg, gif and png images to worksheets with hyperlinks

**8. Refernce cells in your worksheet with "A1" and "A1:D4" style references or from the workbook using "Sheett1!A3:B4" style references

**9. Cell level style overrides for default and customized style object

**10. Support for formulas

**11. Support for cell merging via worksheet.merged_cells

**12. Auto filtering tables with worksheet.auto_filter
