Share Spire.Xls for .NET component here

Question

Recently I want to develop a .NET application related to Excel. Most of my friends recommend Spire.xls for me. But I am not quite sure about it. Then I searched in Google, This spire.xls for .NET is truly in the front, finding it useful, so I would like to make a share here.
