using Ninjanaut.IO;

// From file path
var path = @"C:\FooExcel.xlsx";
var datatable = ExcelReader.ToDataTable(path);

// Or from bytes
var path = @"C:\FooExcel.xlsx";
var bytes = File.ReadAllBytes(path);
var datatable = ExcelReader.ToDataTable(bytes);

you can also use options argument

using Ninjanaut.IO;

var path = @"C:\FooExcel.xlsx";
var options = new ExcelReaderOptions 
    // Default settings:
    Format = ExcelReaderFormat.Xlsx,
    SheetIndex = 0,
    SheetName = null,
    HeaderRowIndex = 0,
    RemoveEmptyRows = true,
    AllowDuplicateColumns = true,
    MaxColumns = null

var datatable = ExcelReader.ToDataTable(path, options);

// The options can be defined within the method.
var datatable = ExcelReader.ToDataTable(path, new() { SheetName = "My Sheet" });


DataTable object is suitable for this purpose, because you can easily view the read data directly in Visual Studio for debug purposes, create a collection of entities from it or pass datatable as parameter directly into the SQL server stored procedure.
