Answer 1

Take a look at Linq-to-Excel. It's pretty neat.

var book = new LinqToExcel.ExcelQueryFactory(@"File.xlsx");

var query =
    from row in book.Worksheet("Stock Entry")
    let item = new
    {
        Code = row["Code"].Cast(),
        Supplier = row["Supplier"].Cast(),
        Ref = row["Ref"].Cast(),
    }
    where item.Supplier == "Walmart"
    select item;

It also allows for strongly-typed row access too.
