Synopsis

Axlsx is an Office Open XML Spreadsheet generator for the Ruby programming language. It enables the you to generate 100% valid xlsx files that include customised styling 3D pie, bar and line charts. Below is a summary of salient features.

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 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 both 1904 and 1900 epocs configurable in the workbook.
