Hey guys,

I am working on a project where I am using a DataReader to read large amounts of data (100,000+ rows, 20+ column) and am streaming those into a worksheet using the SAX OpenXmlWriter methods to avoid high memory usage.  This is working very fast and efficiently so far as I can tell.  However, as I am writing these values I am also storing the maximum length outputted in each column so I can then go on and update the Columns collection in the worksheet to set appropriate default widths when the spreadsheet is opened in Excel.  Very frustratingly the Columns collection is BEFORE the SheetData meaning that there seems to be no way to update it after writing all my data!  If I try to access the Columns collection via the DOM then it loads the whole spreadsheet into memory and causes my app to crash with an OutOfMemoryException.

Do you guys know of any clever way of updating the Columns collection once the SheetData has finished being outputted without forcing the whole document to be loaded into memory or having to go through the WHOLE spreadsheet with an OpenXmlReader and then output it all again to a new sheet with a separate OpenXmlWriter? Any help would be much appreciated.

Cheers,

James.

I have PPTX files generated by users with PowerPoint 2016. The slides have embedded excel worksheets which I need to access for further processing. I am using Open Xml SDK v2.6.1 in my project.

On passing the embedded object stream to the SpreadsheetDocument, using the following code:

using (PresentationDocument pd =PresentationDocument.Open(pptxFile,true)){foreach(SlidePart slide in pd.PresentationPart.GetPartsOfType<SlidePart>()){foreach(EmbeddedObjectPart eoPart in slide.EmbeddedObjectParts){
      using (SpreadsheetDocument sd =SpreadsheetDocument.Open(eoPart.GetStream(),true)){// do some work with worksheets                                var count = sd.WorkbookPart.WorksheetParts.Count();}}}}

I get the following exception:

System.IO.FileFormatException:File contains corrupted data.
at System.IO.Packaging.ZipPackage..ctor(Stream s,FileMode packageFileMode,FileAccess packageFileAccess)
at System.IO.Packaging.Package.Open(Stream stream,FileMode packageMode,FileAccess packageAccess)
at DocumentFormat.OpenXml.Packaging.OpenXmlPackage.OpenCore(Stream stream,Boolean readWriteMode)
at DocumentFormat.OpenXml.Packaging.SpreadsheetDocument.Open(Stream stream,Boolean isEditable,OpenSettings openSettings)
at...

When I open the pptx package and in the embeddings folder rename oleObject1.bin to oleObject1.zip, then see the file information in WinRar, I see that it is SFX Zip volume and not ZipArchive.

The only way I could get the SpreadsheetDocument to open the embedded object stream was to convert the stream to System.IO.Compression.ZipArchive using DotNetZip library.

So I have the following questions:

1. Is there a way to get Open XML SDK to open embedded excel worksheet stream, without explicit transcoding (from SFX Zip volume to Zip Archive)?
2. What is the best way to write the modified stream back into the presentation document? This is important because, the worksheet data will be updated and has to be written back to the host document.
3. Is there another more elegant way to solve this issue?

Note: this issue does not occur when the worksheet is embedded programmatically using OpenXml SDK in the presentation.

Dear experts,

now i have a requirement to develop a translate powerpoint content.

I use OpenXML to extract the data from slide. But the result is all text in the slide.

is there any Class/API to get these text by its container which is in the powerpoint selection pane?

because i will write back the translated text to the same container.

Attach my current code, FYI:

                using (FileStream fs = new FileStream(openFileDialog1.FileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
                {
                    using (SpreadsheetDocument doc = SpreadsheetDocument.Open(fs, false))
                    {
                        using (FileStream fs1 = new FileStream(Path0, FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite))
                        {
                            using (SpreadsheetDocument doc1 = SpreadsheetDocument.Open(fs1, false))
                            {
                                WorkbookPart workbookPart = doc.WorkbookPart;

                                DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbookPart.Workbook.Sheets;

Hello,

How do I set the TextWrappingValue to Around in my C# open xml file.

TableStyle tableStyle = new TableStyle() { Val = "TableGrid" };
                TableLook tableLook = new TableLook() { Val = "04A0" };
                TextWrappingValues tableTextWrapping = TextWrappingValues.Around;
                tableProperties.Append(tableTextWrapping);

I get the following error on the append:
cannot convert from ‘DocumentFormat.OpenXml.Wordprocessing.TextWrappingValues’ to ‘System.Collections.Generic.IEnumerable<DocumentFormat.OpenXml.OpenXmlElement>’

Thanks,

Hi,

I need to automate the Excel Workbook Data Refresh(Source and Pivot table). Can we do this using OpenXML SDK?

I am using VB Script to Refresh the Workbook but this needs excel software in order to open the workbook and do the refresh.

So I am looking for the approach which does not need Excel to be installed to automate the refresh.

Regards,

Vidya Lokesh

When I call the function WorksheetPart.AddNewPart<DrawingsPart>, the result part filename is /xl/drawings/drawing.xml, which is different from what Excel 2013 names it (/xl/drawings/drawing1.xml). Note the "1". This wouldn't matter, except that the Open XML SDK 2.5 Productivity Tool for Microsoft Office won't compare DrawingsPart s created the two different ways.

What's causing this is that line 7719 of DocumentFormat.OpenXml\src\GeneratedCode\package.cs returns the TargetNameConstant which lacks the "1":
internal const System.String TargetNameConstant =@"drawing";

There's a similar issue for part /xl/worksheets/sheet1.xml on lines 9891 & 9897 of the same package.cs file:
internal const System.String TargetNameConstant =@"sheet";

I need to control the name of the DrawingsPart so the Productivity Tool can generate Open-XML-SDK code for me to use in my program. Can you help me? If this requires a change to the Productivity Tool, I have other ideas for enhancements too.

Hello All,

I'm new to OpenXML and my objective is to read an excel document using Powershell. The reading of the document will be on a server where excel is not installed hence the use of OpenXML. The challenge I'm having is understanding the object model in relation to using it in powershell. Below is what I have written so far and I'm stuck at the point of reading each cell. Even though I have content in the excel file it does not appear when I loop through the cells for a given row as illustrated below. Any ideas what I'm doing incorrectly below? This needs to be written in powershell and also to use openxml. The plan is to ultimately use powertools for openxml for other objectives.   Thank you for your help

I need read column width and row height from xml excel 2003 for printing.But I found that is no law.

Fox example:

    Open a xls file and set columns width 1mm、2mm、3mm、4mm、5mm.Then file save as  xml excel 2003.Open xml file，the value of  columns were 9.6、15、23.4、25.8、31.2.It is no law.

    How can I get table column actual width from xml excel 2003?

Hi everyone,

I have a powerpoint file that needs to be repaired each time I try to open it. I have saved a copy of the repaired version and have tried to make the xml exactly the same however powerpoint still wants to repair it. The open XML validator reports no issues. Is there any way to see why powerpoint doesn't like a file? Does the formatting of the XML matter e.g carriage return? 

Many thanks,

Lakhvir

Hi,

I want to fill my Picture Content Control that is located in the headerof my word document with this code: (I have passed content control tag and the image stream via document parameter to this function)

using (WordprocessingDocument wordDocument =

                        string sdtTitle = alias.Val.Value;


                        //if Sdt Content Control is Picture
                        string imageContent = (from xElement in doc.Descendants("Picture") where xElement.Attribute("Id").Value == sdtTitle select xElement.Value).FirstOrDefault();
                        if (imageContent != null)
                        {

                            if (p != null)
                            {

                                // Get the alias.
                                SdtAlias a = p.Elements<SdtAlias>().FirstOrDefault();
                                if (pict != null && a.Val.Value == sdtTitle)
                                {
                                    string embed = null;
                                    Drawing dr = item.Descendants<Drawing>().FirstOrDefault();
                                    if (dr != null)
                                    {

Hello

I created a Custom SmartArt Layout (.glox), Custom SmartArt Color (.gcsx) or a Custom SmartArt QuickStyle (.gqsx).

Discribed on:
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/c4f15db4-90bb-447d-8dd6-bb0afadd218c/smartart-creating-custom-smartart-that-works-with-pictures?forum=officegeneral

I copied them in the Folder: "%APPDATA%\Microsoft\Templates\SmartArt Graphics"

But when i open "Microsoft PowerPoint 2016" (Windows) i see only the Custom SmartArt Layout (.glox).

Is the directory "%APPDATA%\Microsoft\Templates\SmartArt Graphics" correct for the GCSX- and GQSX-File or do i have to store then in an other Directory?

Thanks for your attention.
