How to insert excel data into SQL tables

Hi guys,

I am working on an ASP.NET Core Blazor Server app. I have one to many relationships between Order and OrderDetail entities. I couldn't find a way to insert data into tables from excel upload. Any help would be great.

Thanks in advance.

Here are the entities:

public class Order
{
    public int Id { get; set; }

    [Required]
    public DateTime OrderDateTime { get; set; }
    [Required]
    [MaxLength(250)]
    public string CustomerName { get; set; }
    [Required]
    [MaxLength(250)]
    public string VendorName { get; set; }
    public string Status { get; set; }
    [MaxLength(50)]
    public string DoneBy { get; set; }
    public List<OrderDetail> OrderDetails { get; set; }
}

public class OrderDetail
{
    public int Id { get; set; }

    [Required]
    [MaxLength(100)]
    public string ProductCode { get; set; }
    [Required]
    [MaxLength(250)]
    public string ProductName { get; set; }
    [Required]
    public int BuyQuantity { get; set; }
    [Required]
    public int SellQuantity { get; set; }
    public double CostRatio { get; set; }
    public double UnitCost { get; set; }
    public double TotalBuyPrice { get; set; }
    public double TotalSellPrice { get; set; }
    [MaxLength(150)]
    public string ShippingNumber { get; set; }
    public string Status { get; set; }
    [MaxLength(150)]
    public string TrackingNumber { get; set; }
    [MaxLength(400)]
    public string Description { get; set; }
    public int OrderId { get; set; }
    public virtual Order Order { get; set; }
}

Here is the sample excel:
