Opening the Excel Workbook in share-point without installing the Excel libraries in the Server

The logic goes here:-

There is a excel template file on the server. I read this file using code i.e C#, Excel is installed on my machine and all the things works fine. When using on the Production the same scenario, as excel is not installed the following error occurs which is attached. Kindly suggest me, to overcome this solution. How to overcome this solution without installing the EXCEL on server ?

this code requires Excel to be installed. You cannot use it if you don't install it (which is not recommended on a server). This is why you should use something else like the 2 links I have provided.
