Does EPPlus requires Excel to be installed on the sever ? if Yes, any better alternatives for exporting bulk data using Entity Framework from Server side code to an excel file.
No, it does not require Excel to be installed on the server, as you can read in the docs:
EPPlus is a .NET library that reads and writes Excel files using the Office Open XML format (xlsx). EPPlus has no dependencies other than .NET.
You do need to put the EPPlus assembly on the server though.
