Export Excel and CSV file in Asp.Net Core

Last week I was working on exporting data to Excel and CSV format in AspNet Core so I want to share how I did it. Sample Code: https://github.com/janaks09/ExcelCSVExportInAspNetCore/ Export to Excel: To build Excel file, I am using EPPlus.Core package which is an unofficial port of EEPlus library to .NET Core.
