You can use my SwiftExcel library. It is especially good when performance and low memory usage come in place as it writes data directly to the file:

using (var ew = new ExcelWriter("C:\\temp\\test.xlsx"))
{
    for (var row = 1; row <= 100; row++)
    {
        for (var col = 1; col <= 10; col++)
        {

        }
    }
}

Nuget command to install:

Install-Package SwiftExcel
