Our goal when we started SpreadsheetGear 2008 development was to read from and write to Excel 2007 Open XML (.xlsx) files everything which we support in our API and as many of the elements as possible which previous versions of SpreadsheetGear for .NET could read and write from / to Excel 97-2003 (.xls) files.  Unfortunately, some features supported in the .xls file format currently have limited support or no support in the .xlsx file format.

We intend to support all of these features eventually. We base new features primarily on customer feedback, so let us know what is important to you.

These limitations have not changed with the release of SpreadsheetGear 2009. We are waiting to see what, if anything, Microsoft does to address the issues with Open XML limitations when Office 14 is released. At that time we will revisit issues related to limitations of the Open XML file format and reconsider whether we should support objects which depend on VML.

Issues not related to Open XML file format limitations will be handled as all unimplemented features are. They will be prioritized based on customer feedback, taking into account the amount of work involved in implementing each feature.
