Hello !

I try  open OpenXml with Open xml sdk 2.0 - but it failded.

using (WordprocessingDocument myDoc = WordprocessingDocument.Open(fileName, true)) { }

I have exception : A first chance exception of type 'DocumentFormat.OpenXml.Packaging.OpenXmlPackageException' occurred in DocumentFormat.OpenXml.dll Exception : The specified package is invalid. The main part is missing.

 why ?

Everything happened correctly few months ago. But today I have some problem , maybe it is the reason of windows or microsoft standard updating?

If yes, what shoud I do?

Hi Jolibal,

What is the document you are trying to open? Try opening this in word and see if you get the same issue.

Thanks

Jay

I'm having the same problem.  I created a spreadsheet in Excel, saved as ODS, but when I try reading it I get the error above.  I tried looking at the file but it must be compressed 'cause it's mostly binary.  Excel's File Properties confirms the file is OpenDocument Spreadsheet format.

The code I used to try opening it (with 2.0 SDK) is:

        [TestMethod]
        public void LoadSaveTest()
        {
            var simpleFilePath = // the file's path
            var outputFilePath = // an output file path

            if (!File.Exists(simpleFilePath))
                throw new FileNotFoundException(simpleFilePath);

            var aSheet = SpreadsheetDocument.Open(simpleFilePath, false);
        }

What I want for a test is to simply open the ODS and save it under another name.  After fixing the exception (thrown on the Open()) I need to figure out how to save it.

The Open XML SDK is not able to open ODF formats, such as ODS or ODT.
