Concepts
One of the key goals of ExtremeML is to allow you to get started creating rich and complex Excel spreadsheets, directly from your .NET code, without the need to learn lots of background theory. If this is how you prefer to work, you should jump directly to the tutorials and get started.
On the other hand, there will be times when you need to know what’s happening behind the scenes. This page will be periodically updated with resources that discuss both ExtremeML concepts and the broader topics of OpenXML and SpreadsheetML.
