I'm trying to use DocumentFormat.OpenXml to read an uploaded Excel file. When I get the file (HttpPosteFileWrapper) I'm simply trying to read the cells and write them to a text string. (Later I will do more, but I'm just trying to get used to OpenXml right now.)
My data in Excel looks something like this:
Field1 - Field2 - Phone - City
IT Department - Emp - 7175551234 - Springfield
HR - Emp - 7175556543 - W Springfield
Code looks like this:
var doc = SpreadsheetDocument.Open(file.InputStream, false);
WorkbookPart workbookPart = doc.WorkbookPart;
WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
SheetData thisSheet = worksheetPart.Worksheet.Elements<SheetData>().First();
System.Text.StringBuilder text = new System.Text.StringBuilder();
foreach (Row r in thisSheet.Elements<Row>())
{
foreach (Cell c in r.Elements<Cell>())
{
text.Append(c.CellValue.Text + ",");
}
text.AppendLine();
}
And the string it creates looks like this:
49,51,50,0,1,2,3,4,5,6,7,8,9,10,11,12,13,16,14,15,17,18,19,20,21,22,40,41,42,43,44,45,54,\r\n
52,24,23,25,26,27,7306,33,28,29,30,31,17033,32,34,7175555555,7175551234,7175554321,7175550000,35,36,37,36526,40179,38,39,30,31,17033,32,55,\r\n
53,46,47,48,555,\r\n
It seems like the numeric values come through. Is it because I'm using the wrong stream type?
Edit: I've updated my code to now look like this, but it still doesn't work right. There seems to be no way for me to see the text data.
public ActionResult ProfileImport(IEnumerable<HttpPostedFileBase> files)
{
// Build file list
int i = 1;
foreach (var file in files)
{
if (file.ContentLength > 0)
{
var doc = SpreadsheetDocument.Open(file.InputStream, false);
WorkbookPart workbookPart = doc.WorkbookPart;
WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
SheetData thisSheet = worksheetPart.Worksheet.Elements<SheetData>().First();
System.Text.StringBuilder text = new System.Text.StringBuilder();
foreach (Row r in thisSheet.Elements<Row>())
{
foreach (Cell c in r.Elements<Cell>())
{
string value = c.InnerText;
if (c.DataType != null && c.DataType.Value == CellValues.SharedString) // Check DataType exists
{
var stringTable = workbookPart.GetPartsOfType<SharedStringTablePart>()
.FirstOrDefault(); // Get Table parts from workbookPart
if (stringTable != null)
value = stringTable.SharedStringTable.ElementAt(int.Parse(value)).InnerText;
text.Append(value + ",");
}
else
text.Append(value + ",");
}
text.AppendLine();
}
var outText = text.ToString();
}
}
}
Actual data from 1st row of the file:
AddressDescription, Address1, Address2, City, State, PostalCode, CountryCode, Email, CellPhone, HomePhone, WorkPhone, Fax, OrganizationName, Department, Position, StartDate, EndDate, OrganizationAddress1, OrganizationAddress2 OrganizationCity, OrganizationState, OrganizationPostalCode, OrganizationCountryCode, Keywords
Row.InnerText of that row:
"49515001234567891011121316141517181920212240414243444554"

It looks like these are indices to the strings in the Shared Strings table. In Excel file formats, string data is stored in a shared strings table, which is then references on the cell level. Per the documentation,
CellValue
returns an index to theStringTable
if the data type is text.https://msdn.microsoft.com/en-us/library/documentformat.openxml.spreadsheet.cellvalue%28v=office.14%29.aspx?f=255&MSPPError=-2147217396
Not knowing more about the type of data that's in your cells (there are different ways to retrieve it based on the data type). If it's what I think it is, it'll be a
SharedString
, which you will need to retrieve as a SharedStringTablePart, as shown in this MSDN page:https://msdn.microsoft.com/en-us/library/hh298534%28v=office.14%29.aspx?f=255&MSPPError=-2147217396
Your code would look something like this:
