Currently, I can convert Word to Html using OpenXml with ConvertToHtml method. But I can not apply this method for SpeardSheetDocument file (xlxs). So how can I similarly convert the excel file to Html via OpenXml. Or is there any other approach for my situation ? It would be better if I can convert powerpoint file (ppt) to Html too.
I know there is a library called Interop but if I use this I need to install microsoft office, but I dont want to install those softwares.
Thank all !
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.
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.
Best Regards
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 ;)
Regards.
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 need to convert Word Document to XML and back once editing has been performed on it.
I don't have Microsoft Office Installed at my server, and I want my users to edit their documents via Web Browser.
I am using C# and ASP.Net
Thanks
I believe the latest version of Microsoft Word (and Excel) already save files in XML format, hence the .docx and (.xlsx) extensions. Hope that suffices your need.
Alternatively, you could see if they are tools to convert the old .doc format files to .docx which should, as a result, provide you with a XML based word file.
So you have a couple of options here:
1) Use OfficeWriter from SoftArtisans. This allows you to crack open the binary office file format(e.g. .doc and .xls) note:I am biased because my company makes this product but I think it's awesome.
2) If you can use the newest file format (.docx and .xlsx) you can use the SDK that microsoft has released that will do all of that uzipping rezipping nonsense for you. (called the opem XML SDK)
How to convert Excel file to xml file using .NET framework 3.5
Please tell the approaches
The format of excel sheet is xls and convert to standard xml format
SpreadsheetGear for .NET will let you open a workbook (xls or xlsx format), get the formatted text (such as $5.00) with the IRange.Text property or the unformatted raw value with the IRange.Value property. You can also modify values and recalculate if needed. You would need to use the .NET XML APIs to write out the formatted text or unformatted values to an XML file.
You can download a free trial here if you want to try it yourself.

You can do it in various ways based on your requirement
You can read it like a database using OleDbConnection object to connect to the file and read data
You can use System.IO.Packaging to read office 2007 (xlsx) files
You can also use Excel.Application object model to read information from Excel
It really depends on your requirement what method is effective for you.
