Reading and writing Excel files with c# never got that easy.
You should install MyExcel with NuGet:
Install-Package MyExcel
Or via the .NET Core command line interface:
dotnet add package MyExcel
Either commands, from Package Manager Console or .NET Core CLI, will download and install MyExcel and all required dependencies.
string fileLocation = @"C:\Users\Username\Desktop\MyExcelFile.xlsx";
using (ExcelWriter writer = new ExcelWriter())
{
writer[1, 1] = "First Cell";
writer.SaveAs(fileLocation);
}using (ExcelReader reader = new ExcelReader())
{
reader.FileLocation = fileLocation;
Console.WriteLine(reader[1,1]);
}
