LibreOffice Calc for Application Development

I’m looking at porting/rewriting an application that I’ve done before in Excel and VB6 with ActiveX Grid controls. Code connected to data, grid was for look/feel/presentation/export to XLS, some occasional user input. Looking to get a general feeling as to whether I should consider LibreOffice Calc or go straight to .NET grid controls.

LibreOffice comes with a database frontend, including grid controls, aka table controls. Exporting database data to some spreadsheet format is trivial.
