This showed that the error was Looking at the ECMA-376 standard from here the XML for a Worksheet looks like this: … Read more
Embedding Foreign Objects (PDF, TXT, GIF, etc…) into Microsoft Word using OpenXml 2.0 (Well, in collaboration with COM) I got a lot from this site, so here I asked and answered my own question in order to give back a little on a topic in which I had difficulty finding answers on, hope it helps … Read more
spreadSheet.WorkbookPart.Workbook.CalculationProperties.ForceFullCalculation = true; spreadSheet.WorkbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true; Works for me!
I recommend installing the Open XML 2.5 productivity tool. Then create a blank Excel document that contains the border and color you desire. Open that file in the productivity tool and then click reflect code. It will then give you the C# code that is required to produce that border and background color. The code … Read more

Not sure this is perfect, but I hope it helps. static void Main(string[] args) { DataTable dt = new DataTable(); using (SpreadsheetDocument spreadSheetDocument = … Read more
The s attribute references a style xf entry in styles.xml. The style xf in turn references a number format mask. To identify a cell that contains a date, you need to perform the style xf -> numberformat lookup, then identify whether that numberformat mask is a date/time numberformat mask (rather than, for example, a percentage … Read more
If you use a MemoryStream you can save the changes to a new file like this: byte[] byteArray = File.ReadAllBytes(“c:\\data\\hello.docx”); using (MemoryStream stream = new MemoryStream()) { stream.Write(byteArray, 0, (int)byteArray.Length); using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(stream, true)) { // Do work here } // Save the file with the new name File.WriteAllBytes(“C:\\data\\newFileName.docx”, stream.ToArray()); }
All strings in an Excel worksheet are stored in a array like structure called the SharedStringTable. The goal of this table is to centralize all strings in an index based array and then if that string is used multiple times in the document to just reference the index in this array. That being said, the … Read more
You cannot reference OOXML content via page numbering at the OOXML data level alone. Hard page breaks are not the problem; hard page breaks can be counted. Soft page breaks are the problem. These are calculated according to line break and pagination algorithms which are implementation dependent; it is not intrinsic to the OOXML data. … Read more
I wrote this quick example. It works for me. I only tested it with one dataset with one table inside, but I guess that may be enough for you. Take into consideration that I treated all cells as String (not even SharedStrings). If you want to use SharedStrings you might need to tweak my sample … Read more
