Question

I have a spreadsheet document that has 182 columns in it. I need to place the spreadsheet data into a data table, tab by tab, but i need to find out as I’m adding data from each tab, what is the tab name, and add the tab name to a column in the data table.

This is how I set up the data table.

I then loop in the workbook and drill down to the sheetData object and walk through each row and column, getting cell data.

DataTable dt = new DataTable();
for (int i = 0; i <= col.GetUpperBound(0); i++)
{
    try
    {
        dt.Columns.Add(new DataColumn(col[i].ToString(), typeof(string)));
    }
    catch (Exception e)
    {
        MessageBox.Show("Uploader  Error" + e.ToString());
        return null;
    }
}

dt.Columns.Add(new DataColumn("SheetName", typeof(string)));

However at the end of the string array that I use for the Data Table, I need to add the tab name. How can I find out the tab name as I’m looping in the sheet in Open XML?

Here is my code so far:

using (SpreadsheetDocument spreadSheetDocument = 
           SpreadsheetDocument.Open(Destination, false))
{
    WorkbookPart workbookPart = spreadSheetDocument.WorkbookPart;
    Workbook workbook = spreadSheetDocument.WorkbookPart.Workbook;

    Sheets sheets = 
        spreadSheetDocument
            .WorkbookPart
            .Workbook
            .GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();

    OpenXmlElementList list = sheets.ChildElements;

    foreach (WorksheetPart worksheetpart in workbook.WorkbookPart.WorksheetParts)
    {
        Worksheet worksheet = worksheetpart.Worksheet;

        foreach (SheetData sheetData in worksheet.Elements<SheetData>())
        {
            foreach (Row row in sheetData.Elements())
            {
                string[] thisarr = new string[183];
                int index = 0;
                foreach (Cell cell in row.Elements())
                {
                    thisarr[(index)] = GetCellValue(spreadSheetDocument, cell);
                    index++;
                }
                thisarr[182] = ""; //need to add tabname here
                if (thisarr[0].ToString() != "")
                {
                    dt.Rows.Add(thisarr);
                }
            }
        }
    }
}

return dt;

Just a note: I did previously get the tab names from the InnerXML property of “list” in

OpenXmlElementList list = sheets.ChildElements;

however I noticed as I’m looping in the spreadsheet it does not get the tab names in the right order.

The sheet names are stored in the WorkbookPart in a Sheets element which has children of element Sheet which corresponds to each worksheet in the Excel file. All you have to do is grab the correct index out of that Sheets element and that will be the Sheet you are on in your loop. I added a snippet of code below to do what you want.

int sheetIndex = 0;
foreach (WorksheetPart worksheetpart in workbook.WorkbookPart.WorksheetParts)
{                     
    Worksheet worksheet = worksheetpart.Worksheet;

    // Grab the sheet name each time through your loop
    string sheetName = workbookPart.Workbook.Descendants<Sheet>().ElementAt(sheetIndex).Name;

    foreach (SheetData sheetData in worksheet.Elements<SheetData>())
    {

       ...
    }
    sheetIndex++;
}
