Open XML SDK 2.0 to get access to excel 2010 worksheet by name

Question

I have an Excel 2010 spreadsheet that has 3 worksheets named Sheet1, Sheet2 and Sheet3.

I\'m trying to get a reference to a worksheet by name.

I\'m using the co

Here is some code to process a spreadsheet with a specific tab or sheet name and dump it to something like CSV. (I chose a pipe instead of comma).

I wish it was easier to get the value from a cell, but I think this is what we are stuck with. You can see that I reference the MSDN documents where I got most of this code. That is what Microsoft recommends.

    public void WriteOutExcelFile()
    {
        var fileName = "ExcelFiles\\File_With_Many_Tabs.xlsx";
        var sheetName = "Submission Form"; // Existing tab name.
        using (var document = SpreadsheetDocument.Open(fileName, isEditable: false))
        {
            var workbookPart = document.WorkbookPart;
            var sheet = workbookPart.Workbook.Descendants().FirstOrDefault(s => s.Name == sheetName);
            var worksheetPart = (WorksheetPart)(workbookPart.GetPartById(sheet.Id));
            var sheetData = worksheetPart.Worksheet.Elements().First();

            foreach (var row in sheetData.Elements())
            {
                foreach (var cell in row.Elements())
                {
                    Console.Write("|" + GetCellValue(cell, workbookPart));
                }
                Console.Write("\n");
            }
        }
    }

    private string GetCellValue(Cell cell, WorkbookPart workbookPart)
    {
        if (cell == null)

            return null;
        }

        var value = cell.CellFormula != null
            ? cell.CellValue.InnerText 
            : cell.InnerText.Trim();

        // If the cell represents an integer number, you are done. 
        // For dates, this code returns the serialized value that 
        // represents the date. The code handles strings and 
        // Booleans individually. For shared strings, the code 
        // looks up the corresponding value in the shared string 
        // table. For Booleans, the code converts the value into 
        // the words TRUE or FALSE.
        if (cell.DataType == null)
        {
            return value;
        }
        switch (cell.DataType.Value)
        {
            case CellValues.SharedString:

                // For shared strings, look up the value in the
                // shared strings table.

                    workbookPart.GetPartsOfType()
                        .FirstOrDefault();

                // is wrong. Return the index that is in
                // the cell. Otherwise, look up the correct text in 
                // the table.
                if (stringTable != null)
                {
                    value =
                        stringTable.SharedStringTable
                            .ElementAt(int.Parse(value)).InnerText;
                }
                break;

            case CellValues.Boolean:
                switch (value)
                {
                    case "0":
