I'm trying to change the width of some excel columns. I've tried everything but I keep getting empty excel documents, my excel file works fine without this addition: Columns columns = new Columns(); columns.Append(new Column() { Min = 1, Max = 3, Width = 20, CustomWidth = true }); columns.Append(new Column() { Min = 4, Max = 4, Width = 30, CustomWidth = true }); wsPart.Worksheet.Append(columns); But as soon as I add this like this user suggested , I have to repair my excel file, and it will be empty. I get this error: "Replaced Part: /xl/worksheets/sheet.xml part with XML error. Load error.

I'm using OpenXML SDK2.0 for excel calculations and stuck with 1 thing. Basically I'm populating an excel file with data from database and sending it to the user...that bit works fine. Now I want to get the calculated cell value after I'm putting a formula in it, but without opening the excel document... Is there a way to populate excel file with openxml sdk2.0 and get calculated values back straight away? Maybe someone has encountered similar problem or has a working solution ! Thanks:) spreadSheet.WorkbookPart.Workbook.CalculationProperties.ForceFullCalculation = true; spreadSheet

I'm using OpenXML to create Microsoft Excel file. I'm trying to insert a double type variable (Example : 4.987456789) into the Excel using Cell cell = new Cell() { CellReference = "A2", DataType = CellValues.String, CellValue = new CellValue(Convert.ToString(value)) }; But, when the cell is being made, it's in text form and Excel says "The number in this cell is formatted as text or preceded by an apostrophe." How can format the cell to insert double? Edit : Sorry, It's double? type and I follow this tutorial Using CellValues.Number works fine for me, for example : double? value = 4.9874567891

I am trying to get the first 4 rows of an xlsx file to repeat at the top of each page when printed. I am using the Open XML SDK to accomplish this. My file is being generated by the SSRS execution web service as a filestream. I then need to modify several layout and page settings (margins, page size, zoom, etc) before delivering the file to the user, as my users have very little Excel acumen. All other settings I need to tweak are working correctly, so I have stripped out all of that code from this example.
