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 !

Does ClosedXML have any function that can be used to save an excel file as PDF?
Currently i am using ClosedXML to create and populate the excel file and then using Interop to save as PDF.
But since Interop depends on the MS Office installed on the syatem the formatting changes on every version of MS Office. And since ClosedXML doesnt require having MS office installed it would be nice to be able to export or save as PDF directly from it without using Interops.

No.
Instead you can use the free version of GemBox.Spreadsheet.
Also look at the top 10 libraries which allows us to manipulate excel.
However GemBox was the only free and featured one that I found with the purpose of creating an invoice report for a website, by converting excel to pdf.
you can use the ClosedXML.Excel and iTextSharp to convert Excel to PDF file.
Here a link with example:

I am trying to export a word document in HTML using Microsoft.Office.Interop.Word. Unfortunately the only formats supported for export are PDF and XPS. Is there a way to work around this and force export to html or should I rather use COM?
any library that would allow me to export into HTML?
Try Document.SaveCopyAs with wdFormatHTML. Recording a macro when you save the word document as HTML should help you figure out the parameters.
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.

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 have a csv file and I need to make a pdf copy in the console application that creates the csv. All I have found 3rd party libraries for working with pdf but I don't want to use that. Can I just make a copy and save it as a pdf? If so, how?
