Thank you for your interest in RadSpreadsheet.
The control's document model
is completely decoupled from UI. What this means is that you can convert or import and modify documents in a WPF application without any UI related to RadSpreadsheet.
Please note that xls documents are currently not supported, the supported formats are xlsx, csv and txt. More about the control is available in its online documentation
and I'd suggest you also check our SDK examples
, particularly this one
demonstrating document conversion.
I hope this helps! Let us know if you need any further assistance.
