The .NET Library EPPlus implements a conversation from the string definition to the built in number. See class ExcelNumberFormat:

internal static int GetFromBuildIdFromFormat(string format)
{
    switch (format)
    {
        case "General":
            return 0;
        case "0":
            return 1;
        case "0.00":
            return 2;
        case "#,##0":
            return 3;
        case "#,##0.00":
            return 4;
        case "0%":
            return 9;
        case "0.00%":
            return 10;
        case "0.00E+00":
            return 11;
        case "# ?/?":
            return 12;
        case "# ??/??":
            return 13;
        case "mm-dd-yy":
            return 14;
        case "d-mmm-yy":
            return 15;
        case "d-mmm":
            return 16;
        case "mmm-yy":
            return 17;
        case "h:mm AM/PM":
            return 18;
        case "h:mm:ss AM/PM":
            return 19;
        case "h:mm":
            return 20;
        case "h:mm:ss":
            return 21;
        case "m/d/yy h:mm":
            return 22;
        case "#,##0 ;(#,##0)":
            return 37;
        case "#,##0 ;[Red](#,##0)":
            return 38;
        case "#,##0.00;(#,##0.00)":
            return 39;
        case "#,##0.00;[Red](#,#)":
            return 40;
        case "mm:ss":
            return 45;
        case "[h]:mm:ss":
            return 46;
        case "mmss.0":
            return 47;
        case "##0.0":
            return 48;
        case "@":
            return 49;
        default:
            return int.MinValue;
    }
}

When you use one of these formats, Excel will automatically identify them as a standard format.
