I am unable to write data to Excel binary ".xlsb" file using openxml with c#
i want to use it for writing data to binary "xlsb" file using c# but without excel interpro.
i tried openxml but it is not working.
Unfortunately Open XML SDK cannot handle .xlsb files since they are stored as binary. The Office XML Formats which Open XML SDK could recognize are based on XML and ZIP technologies, rather than binary. Generally Open XML SDK could handle spreadsheets like ".xlsx", "xlsm", "xltx" and so on.
i found it in https://social.msdn.microsoft.com/Forums/office/en-US/bf78ca1d-50dd-4690-8bc6-fbcdecacddb3/handle-xlsb-files?forum=oxmlsdk
In my application I already have functionality to export into 2003 format. Where I am constructing a string out of the template and write using System.IO.File.WriteAllText.
But it does not work with excel 2007/2010, that's why I wanted to convert it to Openxml in order to support 2007 and 2010.
I have string ready with creation of cells and rows from template.
I want advice on how to achieve or any body has reference link.
Please let me know.
Regards
WriteAllText class will save you a text file. You are saving an html(text) based file with xls extension. This is not a real xls file (that is actually a binary file), but MS Excel recognize and interpret the html format.
An xlsx file is a binary file. You can use OpenXML Office library ( Excel.XlFileFormat.xlOpenXMLWorkbook ) or another .NET Excel library like EasyXLS. Check this sample of code for more details.
I am obtaining data from a database that is returned in an XML string. What is the best way to then store this in an Excel file? Is there an XML - Excel tool, or is there an interim step?
Thanks.
The easiest way is probably just to loop through the XML-data either with XMLDocument or XDocument (linq) and write to a csv-file. The advantage with at csv file is that its readable with any text editor or other spreadsheet software.
You can read the data using the XMLDocument and then insert the data in the excel using Microsoft.Excel namespace.
Providing you're talking about Excel 2007 or newer, the format is XML-based. Check out any resources on OpenXML such as http://openxmldeveloper.org/ for details, or there's a video tutorial here that shows it http://www.asp.net/linq/videos/how-do-i-create-excel-spreadsheets-using-linq-to-xml . There's even things like http://code.google.com/p/linqtoexcel/ and an SDK here http://www.microsoft.com/downloads/en/details.aspx?FamilyId=C6E744E5-36E9-45F5-8D8C-331DF206E0D0&displaylang=en .
Simple question. Does anyone know an easy way to convert SpreadsheetML (Excel 2003 XML) to the Open Document XML used for Excel 2007 (xlsx) files?
I've got a library that unfortunately doesn't read the XML format, so I need to try and find a way to read the data, that doesn't involve another library.
Any suggestions appreciated.
If you've got deep pockets Aspose.Cells can read/write both formats and should provide for really easy conversion without automation.

Aspose.Cells for .NET
Aspose.Cells for .NET is an award-winning Spreadsheet component that allows .NET developers to embed the ability to read, write and manipulate Excel spreadsheets into their own applications without needing to rely on Microsoft Excel.
Aspose.Cells for .NET is a mature, scalable and feature rich component that offers many functions that are way beyond the simple data exporting capabilities of other vendors. With Aspose.Cells for .NET developers can export data, format spreadsheets to the most granular level, import images, import charts, create charts, apply and calculate complex formulas, stream Excel data, save in various formats and much more - all this without the need to use Microsoft Excel or Microsoft Office Automation.
Pricing starts at $899 per developer for enterprise (internal) development and goes up from there very steeply.
The file format has indeed changed significantly from SpreadsheetML to Office Open XML.
And, since now spreadsheet files are broken into multiple XML files (which are all then zipped), there's no real hope of an easy XLST solution.
The most straightforward course of action, unfortunately, is to automate Excel using a macro to open each SpreadsheetML files and do a "Save As" to the newer format. This can be done in Office 2003 with the Office 2007 file format plug-in. Perhaps this can be relegated to a batch process so the server is not directly involved?
If the data in the spreadsheets are trivial and follow a consistent format, you can write your own parser to import directly from the SpreadsheetML files.
An easy way would be to use Excel's COM Library (Excel 2007), but I think that's not the answer you are looking for.
What's your library capable of? You could use the Open XML SDK 2.0 to write the spreadsheet document based on the output of your library.

Try using JODConverter. JODConverter allows conversion of SpreadsheetML using the OpenOffice.org or Libreoffice engine.
IIRC the Office 2003 format works like OpenDocument format: It's a ZIP file with XML files inside, so (if you have enough time/courage) you can open it, find the XML file that contains the data and finally deal with XML.
I know, this answer is for brave developers ;)

check this code static void XlsToXlsx
static void XlsToXlsx (string sourceFile, string destinationFile)
{
Type officeType = Type.GetTypeFromProgID("Excel.Application");
Excel.Application app = new Excel.Application();
app.DisplayAlerts = false;
// Open Excel Workbook for conversion.
Excel.Workbook excelWorkbook = app.Workbooks.Open(sourceFile);
// Save file as CSV file.
//excelWorkbook.SaveAs(destinationFile, Excel.XlFileFormat.xlCSV);
excelWorkbook.SaveAs(destinationFile, Excel.XlFileFormat.xlOpenXMLWorkbook);
// Close the Workbook.
excelWorkbook.Close();
// Quit Excel Application.
app.Quit();
}
I want to create XML file from my Excel file through .NET (c#). My data is in Excel and it will be added in XML file.
Thanks.

There is good article in CodeProject about it. Generally the answer is, that Excel can be used as Data provider. Later, when you get data out, you can use XMLDom to generate XML file
