Support Requests
If you need specific help on using SpreadsheetLight (or even just Open XML in general, spreadsheets or not, Open XML SDK or not), you can contact me here and I will get back to you as soon as I can.
In the meantime, there’s example source code, an FAQ and even detailed MSDN-like documentation. You might find your answer there.
