Yay! My new article on Excel, OpenXML and PHP has just been released in php|architect! A copy-paste action from http://www.phparch.com/issue.php?mid=102:
"A few months ago, Microsoft released Office 2007, a version of their office suite that generates open source documents. Here, Maarten Balliauw gives an overview of the history and the politics surrounding the release before moving on to introduce his PHPExcel project, an early adoption of Microsoft's OpenXML API that enables Excel 2007 spreadsheets to be generated with PHP."
