How to get OleDb for reading excel in asp.net core project

Question

Is there any way of reading excel data in ASP.NET Core (built over .Net Core)? I am not able to refer OleDB in project.json of my .net

Answer 1

As indicated by andrews, it is recommended to use a third-party library, especially when working with formatting. An alternative to ClosedXML is EPPlus. For most of my project I have used ClosedXML, but I had to switch to EPPlus because it has support for charts.

For ASP.NET Core, you can use EPPlus.Core. I have performed a quick test within an ASP.NET Core 2.0 console app and it seems to work fine:

var newFile = new FileInfo("some file.xlsx");
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{
   var ws = xlPackage.Workbook.Worksheets.Add("etc");
   ws.Cells[1, 1].Value = "test";

   // do work here 
   xlPackage.Save();
}
