As of Now, What is the Best/fastest method to Process Excel via C# Code


Question to experienced C# developers.

At present, what is the best method/library to use when handling Excel related processing (such as reading, writing, etc)?

Ive read on old articles that it is best done via OleDB or OpenXML because of their speed.
Is this still the case today? or is there a new better/faster alternative?

Hi @mayuyu,

I am not expericed as much in c#. But I have used Spire.XLS package for Excel Operations.
