I am trying to create a simple excel file with multiple sheets using open xml, unfortunately the file does not open after it's being created.
After the file is generated, when I open it with Microsoft Excel it says
We found a problem, do you want to recover as much as we can?
using (SpreadsheetDocument spreedDoc = SpreadsheetDocument.Create(filePath,
DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
{
WorkbookPart wbPart = spreedDoc.WorkbookPart;
wbPart = spreedDoc.AddWorkbookPart();
wbPart.Workbook = new Workbook();
Sheets sheets = wbPart.Workbook.AppendChild(new Sheets());
foreach (var sheetData in excelSheetData)
{
// Add a blank WorksheetPart.
WorksheetPart worksheetPart = wbPart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet(new SheetData());
string relationshipId = wbPart.GetIdOfPart(worksheetPart);
// Get a unique ID for the new worksheet.
uint sheetId = 1;
if (sheets.Elements<Sheet>().Count() > 0)
{
sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
// Give the new worksheet a name.
string sheetNameToWrite = sheetName;
if (string.IsNullOrWhiteSpace(sheetNameToWrite))
{
sheetNameToWrite = "Sheet"+sheetId;
}
// Append the new worksheet and associate it with the workbook.
Sheet sheet = new Sheet() { Id = relationshipId, SheetId = sheetId, Name = sheetName };
sheets.AppendChild(sheet);
}
//wbPart.Workbook.Sheets.AppendChild(sheet);
wbPart.Workbook.Save();
}
On trying to Repair in excel gives below message
-<repairedRecords summary="Following is a list of repairs:">
<repairedRecord>Repaired Records: Worksheet properties from /xl/workbook.xml part (Workbook)</repairedRecord>
</repairedRecords>
</recoveryLog>

The necessary steps to create a functional excel file with multiple worksheets in OpenXML (that work for me) are as follows:
using (SpreadsheetDocument spreadsheet = SpreadsheetDocument.Create(path, SpreadsheetDocumentType.Workbook))
{
spreadsheet.AddWorkbookPart();
spreadsheet.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();
spreadsheet.WorkbookPart.Workbook.Append(new BookViews(new WorkbookView()));
WorkbookStylesPart workbookStylesPart = spreadsheet.WorkbookPart.AddNewPart<WorkbookStylesPart>("rIdStyles");
Stylesheet stylesheet = new Stylesheet();
workbookStylesPart.Stylesheet = stylesheet;
workbookStylesPart.Stylesheet.Save();
for (int worksheetNo = 1; worksheetNo < worksheetCountYouWantToCreate; worksheetNo++)
{
string workSheetID = "rId" + worksheetNo;
string worksheetName = "worksheet" + worksheetNo;
WorksheetPart newWorksheetPart = spreadsheet.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet();
newWorksheetPart.Worksheet.AppendChild(new DocumentFormat.OpenXml.Spreadsheet.SheetData());
// write data here
// ...
// ...
newWorksheetPart.Worksheet.Save();
if (worksheetNo == 1)
spreadsheet.WorkbookPart.Workbook.AppendChild(new DocumentFormat.OpenXml.Spreadsheet.Sheets());
spreadsheet.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>().AppendChild(new DocumentFormat.OpenXml.Spreadsheet.Sheet()
{
Id = spreadsheet.WorkbookPart.GetIdOfPart(newWorksheetPart),
SheetId = (uint)worksheetNo,
Name = worksheetName
});
}
spreadsheet.WorkbookPart.Workbook.Save();
}

I'm fairly new to creating Excel spreadsheets in C# and I'm looking for advice.
I've spent 2 or 3 days now looking through documentation and blogs etc but I cannot seem to find an answer to a common task.
I need to insert a text value into a specific worksheet. I cant easily post my code at the moment but it appears to be an issue with every example I've seen of the definition of a sheet, it always gets the first child.
I need to iterate through all sheets and dependant on the sheet name then go and insert a value.
I.e. If the sheet name = "testA" then write TestA, if the sheet name = "testB" then write "TestB".
Currently I can insert a value for the workbook but it inserts the same value for every sheet.
Sheets sheets = workbookPart.Workbook.GetFirstChild<Sheets>();
[Microsoft documentation] (https://learn.microsoft.com/en-us/office/open-xml/how-to-insert-text-into-a-cell-in-a-spreadsheet)
Please note I'm not just giving up on this I've just reached a bit of a wall with it and need some pointers.
Many Thanks, J

The following method creates a new workbook, and inserts two validator dropdowns:
public static void ForValidator() {
using (SpreadsheetDocument myDoc = SpreadsheetDocument.Create("validator output.xlsx", SpreadsheetDocumentType.Workbook)) {
WorkbookPart workbookpart = myDoc.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
SheetData sheetData_ = new SheetData();
worksheetPart.Worksheet = new Worksheet(sheetData_);
Sheets sheets_ = myDoc.WorkbookPart.Workbook.AppendChild(new Sheets());
sheets_.AppendChild(new Sheet() {
Id = myDoc.WorkbookPart.GetIdOfPart(myDoc.WorkbookPart.WorksheetParts.First()), SheetId = 1, Name = "Sheet1"
});
DataValidations dataValidations = new DataValidations();
DataValidation dataValidation = new DataValidation() {
Type = DataValidationValues.List, AllowBlank = true, SequenceOfReferences = new ListValue<StringValue>() { InnerText = "F2:F3" }
};
Formula1 formula = new Formula1();
formula.Text = "\"Selection 1,Selection 2,Selection 3\"";
dataValidation.Append(formula);
dataValidations.Append(dataValidation);
worksheetPart.Worksheet.AppendChild(dataValidations);
}
}
Can the same routine be modified to instead just open an existing "validator output.xlsx" file and do the same thing?
For over a week I've tried everything I know to try and have come up with nothing. Thank you for any help.
I am using OpenXML to manipulate Excel files.
I am sending the Excel files as memory stream, editing them and then send them back to browser so they open in client office program. I create new spread sheet by using this code:
public static void InsertWorksheet(string docName)
{
using (SpreadsheetDocument spreadSheet = SpreadsheetDocument.Open(docName, true))
{
// Add a blank WorksheetPart.
WorksheetPart newWorksheetPart = spreadSheet.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new Worksheet(new SheetData());
Sheets sheets = spreadSheet.WorkbookPart.Workbook.GetFirstChild<Sheets>();
string relationshipId = spreadSheet.WorkbookPart.GetIdOfPart(newWorksheetPart);
// Get a unique ID for the new worksheet.
uint sheetId = 1;
if (sheets.Elements<Sheet>().Count() > 0)
{
sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
// Give the new worksheet a name.
string sheetName = "Sheet" + sheetId;
// Append the new worksheet and associate it with the workbook.
Sheet sheet = new Sheet() { Id = relationshipId, SheetId = sheetId, Name = sheetName };
sheets.Append(sheet);
}
}
My problem is that this sheet is added last among the sheets in the workbook. I want it to be sheet nr 1. I am looking for tips on how I can set my newly created sheet to be sheet nr. 1.
Maybe instead of sheets.Append you call something that inserts it at the beginning? is there a Insert or Prepend method?
What im trying to do is create multiple worksheets within a work book using datasets the code i have to create a sheet data object from a data set is:
public static SheetData CreateDataSheet(DataSet ds)
{
var xlSheetData = new SheetData();
if (ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0)
{
var tbl = ds.Tables[0];
foreach (DataRow row in tbl.Rows)
{
var xlRow = new Row();
foreach (DataColumn col in tbl.Columns)
{
var cellData = row[col];
Cell xlCell = null;
if (cellData != null)
{
xlCell = new Cell(new InlineString(new Text(cellData.ToString())))
{
DataType = CellValues.InlineString
};
}
else
{
xlCell = new Cell(new InlineString(new Text(String.Empty)))
{
DataType = CellValues.InlineString
};
}
xlRow.Append(xlCell);
}
xlSheetData.Append(xlRow);
}
}
return xlSheetData;
}
Then to create the spreadsheet and append the above to the spreadsheet i have:
public static void CreateSpreadsheetWorkbook(string filepath, List<SheetData> sd)
{
var spreadsheetDocument = SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.Workbook);
var workbookpart = spreadsheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
foreach (var x in sd)
{
var newWorksheetPart = spreadsheetDocument.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new Worksheet(x);
var sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
uint sheetId = 1;
if (sheets.Elements<Sheet>().Any())
{
sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
var sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(newWorksheetPart), SheetId = sheetId, Name = "mySheet" + sheetId };
sheets.Append(sheet);
workbookpart.Workbook.Save();
}
spreadsheetDocument.Close();
}
This runs with out any errors however when i come to open the document its unable to be opened because it is corrupt.
EDIT - final working version:
public static void CreateSpreadsheetWorkbook(string filepath, List<SheetData> sd)
{
var spreadsheetDocument = SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.Workbook);
var workbookpart = spreadsheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
var sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
foreach (var x in sd)
{
var newWorksheetPart = spreadsheetDocument.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new Worksheet(x);
sheets = spreadsheetDocument.WorkbookPart.Workbook.GetFirstChild<Sheets>();
uint sheetId = 1;
if (sheets.Elements<Sheet>().Any())
{
sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
var sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(newWorksheetPart), SheetId = sheetId, Name = "mySheet" + sheetId };
sheets.Append(sheet);
workbookpart.Workbook.Save();
}
spreadsheetDocument.Close();
}
After comparing with some similar code of mine I found these possible problems:
var spreadsheetDocument = SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.Workbook);
//should be
var spreadsheetDocument = SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.DocumentType);
And
var sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
//should be
var sheets = spreadsheetDocument.WorkbookPart.Workbook.GetFirstChild<Sheets>();
after the first time since by the second time you already have a Sheets element.
See this blogpost for more details:
http://blogs.msdn.com/b/brian_jones/archive/2009/02/19/how-to-copy-a-worksheet-within-a-workbook.aspx
When I follow this tutorial:
http://msdn.microsoft.com/en-us/library/cc881781.aspx
to open an Excel document and insert an empty worksheet the final result is a message telling "Excel found unreadable content in ... Do you want to recover the contents of this workbook...". If I recover all the inserted sheets are blank (even if I add content programatically)
After renaming the xlsx to .zip and examining it shows that the worksheets have been created, and content added.
Anyone with any similar problems? It may be something with not creating relationships between newly created parts...
That error message means that the XML that makes up your excel document is not conforming to the XML Schema and is invalid. You can use the Open XML SDK 2.0 Productivity Tool to see where the issue is located.
I also copied the code from the bottom of your link and got it to work like Chris said in his comment. Does your code look like this below?
// Open the document for editing.
using (SpreadsheetDocument spreadSheet = SpreadsheetDocument.Open(docName, true))
{
// Add a blank WorksheetPart.
WorksheetPart newWorksheetPart =
spreadSheet.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new Worksheet(new SheetData());
Sheets sheets = spreadSheet.WorkbookPart.Workbook.GetFirstChild<Sheets>();
string relationshipId =
spreadSheet.WorkbookPart.GetIdOfPart(newWorksheetPart);
// Get a unique ID for the new worksheet.
uint sheetId = 1;
if (sheets.Elements<Sheet>().Count() > 0)
{
sheetId =
sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
// Give the new worksheet a name.
string sheetName = "Sheet" + sheetId;
// Append the new worksheet and associate it with the workbook.
Sheet sheet = new Sheet()
{ Id = relationshipId, SheetId = sheetId, Name = sheetName };
sheets.Append(sheet);
string docName = #"C:\Users\Public\Documents\Sheet7.xlsx";
InsertWorksheet(docName);
}
// Given a document name, inserts a new worksheet.
public static void InsertWorksheet(string docName)
{
// Open the document for editing.
using (SpreadsheetDocument spreadSheet = SpreadsheetDocument.Open(docName, true))
{
// Add a blank WorksheetPart.
WorksheetPart newWorksheetPart = spreadSheet.WorkbookPart.AddNewPart<WorksheetPart>();
newWorksheetPart.Worksheet = new Worksheet(new SheetData());
Sheets sheets = spreadSheet.WorkbookPart.Workbook.GetFirstChild<Sheets>();
string relationshipId = spreadSheet.WorkbookPart.GetIdOfPart(newWorksheetPart);
// Get a unique ID for the new worksheet.
uint sheetId = 1;
if (sheets.Elements<Sheet>().Count() > 0)
{
sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
// Give the new worksheet a name.
string sheetName = "Sheet" + sheetId;
// Append the new worksheet and associate it with the workbook.
Sheet sheet = new Sheet() { Id = relationshipId, SheetId = sheetId, Name = sheetName };
sheets.Append(sheet);
}
}
