Is it possible to import excel data to display using C# in any view(data grid etc ..) while retaining formatting like Bold, italic and strikethrough, throughout the document? I am making a Windows form application. My data is in an excel sheet, I want to display it in grid view or any other while retaining the formatting.
Well, there are some ways that I can think of but neither of them are very pretty at all and they would not be very effecient.
1) Parse the excel file cell by cell using Excel Interop. (Very nasty)
2) If you can convert the excel file to Excel XML you could then write say a XSLT to parse the file to pull styling data much more quickly.
Of course getting the styling data out is one thing. Applying it can be a whole other experience. Once you get the styling you have to make sure you apply the values to all the correct columns. Again very nasty and alot of parsing.
However since you did not say whether this was a web or desktop app you could always just embedd an excel control (on the web side) to display the data which may solve your problem. On a desktop app you are probably in for a world of pain trying to do what I describe above.
Maybe somebody will have a better answer but that's what I got.
SpreadsheetGear for .NET can load Excel workbooks and provides access to formatted text values as well as cell formatting such as fonts and colors.
SpreadsheetGear also comes with a Windows Forms spreadsheet control which will allow users to display, edit, format, calculate, print, etc... workbooks with formatting, charts, etc... intact.
If you are building an ASP.NET application, you can use SpreadsheetGear to open a workbook and generate an image of cells and / or charts as shown on our "Excel Chart and Range Imaging Samples" page here
You can download the free trial here if you want to try it out.

I have spent the last 2 hours researching how to embed an excel file along with its formulas for a few cells and display it in a Winform application so the user can enter values and also the c#app can modify cell values based on some other resource data that is fed in via a USB port.
I cannot find any method other than these two - the first isn't supported and the other is 16 years old. Is this possible / supported to embed an excel sheet in a c# application?
Please note, I do not want to open the excel sheet and copy the data into a datagrid or similar as i need to use excel's functionality of conditional formulas to turn cells green if certain criteria are met etc etc the list of excel benefits goes on here. There are hundreds of these conditional formatting and embedded upper/lower limits in an existing excel file and i just want to embed the file and use excel's already excellent functionality.
Method 1 DSOFramer - No longer supported
Method 2 https://www.codeproject.com/Articles/15760/How-to-Integrate-Excel-in-a-Windows-Form-Applicati
using interop.excel with c# you can open excel, show it, interact with it using events to capture cell entry and cell change. its not embedded in the form but the end result is the same.
I don't mind using any external libraries in order to achieve this. I need to get the HTML representation of a Cell Range in Excel (including all formatting such as borders, font style, etc) inside my C# application. We're trying to automate a process where the user copies certain ranges from some excel files to another system.
I've tried using NPOI, COM Interop, OpenXML, and it seems there are no built-in ways to export just a smaller part of a workbook to HTML. NPOI does have a converter for old formats though, but it converts the entire file. And I could use a XLST transformation to convert the OpenXML representation to HTML. But it would take a lot of time which I don't exactly have right now.
Am I missing something? How does Excel itself save its files to HTML format? Can I use this to my advantage somehow? Are there any libraries out there able to do this?
I've done a lot of research but found nothing.
Is there a way to do this in browser? (no AutomationFactory)
I know that I can export as CSV fine but I want to export my Silverlight datagrid as a Excel (.xls) document with the background colors of some rows set.
If you want to interact with MS Excel using Silverlight CLR - it is the only way to use AutomationFactory (becouse of silverlight pesmission restrictions). Ms Excel should be installed on client machines.
But you can also pass data to web-service, process it, and return excel sheet as byte array.
I suggest you use the second way.
I found this guide which is pretty much what I needed, although it is not elegant. Basically, loop through and print all the rows into XML format. I find it very strange that Microsoft would not provide an in-browser method to export to an Excel format and we need to do stuff like this

Export grid from silverlight to excel mht will work for any colors and formattings.
There is some code/werbparts on our site that display a lot of data in a grid on our site. In addition, they have another page with a few charts.
I need a way to create functionality to export this to excel so the user can click a button and save everything.
The chart will actually have to be built in excel, I can't just grab the picture from the website and display it.
Also, the data from the grid will have to be put into a spreadhseet. I am not as worried about this part.
I have exported to excel before, but it was just basically printing some data which was tab delimited with a certain doc type .
This actually will need to use different work sheets and use some excel functionality.
(I need a better answer than use excel services)
Thanks!
Use Epplus is a third party library for creating and manipulating excel files(xlsx)
Dunno about sharepoint, but the OpenXML SDK might be what you're after:-

I would like to display Excel SpreadSheet on the webpage. Seems like when I am using ADO.NET I can only access to data but is there some way so I can also know which rows/cols are formatted in special way like headers?
You can to use Open XML SDK 2.0 for Microsoft Office
SpreadsheetGear for .NET can render a range of cells, or a chart, as an image with custom number formats, fonts, colors, borders, charts, etc...
You can see some live ASP.NET samples (C# and VB) of this here and download the free trial here if you want to try it yourself.
