Yes, only you know what to expect when reading a text file ... what are the delimiters, how many columns, what type of values are in each column, so it is quite a lot to expect software to parse a plain text file and get it right. Excel tries and gets it wrong a significant number of times. Too often eliminating leading zeros for example.
However, I will say that if you parse each row into a well-constructed object. You can pass a list of those objects to the InsertTable method and you have the whole Excel sheet created with one method call. Headings and all.
Such simplicity can't be beat.
example:
sheet.Cell(1, 1).InsertTable(listOfRowObjects)

New Post: Text File Imports
roberttanenbaum: I'm sorry, no disrespect intended, but that is simply incorrect. I was using another library which also uses Open XML as its backbone and was able to import text files directly to a spreadsheet without issue. The only requirement was establishing what the import options were, and that was a simple line of code for each field. The import itself was a single line of code. I didn't have to parse anything; the library did it for me.
Additionally, there are other "helper" libraries which can handle parsing text files just fine. I ask the question here because ClosedXML worked great for handling data down from a database, but I didn't see anything in the documentation addressing text file imports. Now I know ClosedXML doesn't do them, and that's fine. It does what it can do very well. But the other library I use can do this also, and handle the text imports, so I guess for doing those things I'll have to stay with that one.
I don't mean to be argumentative, but I know for a fact some Open XML libraries can do this, out of the box. I use one now.

I'm trying to create a COM component using ClosedXML. It's working perfectly until I go to save the file. Everything works fine when I run a COM test under .NET, but when I connect it to VB6 it pitches the following error.
'System.IO.IsolatedStorage.IsolatedStorageException' occurred in System.Xml.dll
Unable to determine the identity of domain.
The files written are above 10MB. I've research this for about 2 weeks now and still haven't found a resolution.

With Excel, the program wouldn't let you select a value not in the list. With ClosedXML you're responsible for setting a valid value.

Created Unassigned: Cross-worksheet Cell and Range hyperlinks should work [9392]
The XLHyperlink constructor currently converts a Cell or Range into an address string __without the sheet name__. This means that cross-worksheet hyperlinks don't work correctly. If I create a hyperlink on Sheet1 to a Cell on Sheet2, then it gets saved out as a hyperlink to the cell address on Sheet1.
I'm attaching a patch that solves this problems by storing the Cell or Range. ToString is also overloaded so that it can include the sheet name. (ToStringFixed and ToStringRelative already have this overload, but they cannot be used because the Cell or Range may be either fixed or relative.)

New Post: Excel 2013 - 2010 compatibility
Hi first time posting, I figured out how to fix this after reading your posts above and this here
http://support.microsoft.com/kb/296492
TLDR see below for solution if you get the x' was an undeclared namespace problem that I did
1) Download notepad++ so you can edit your XML file easier, you can also choose to use regular notepad
2) For the noobs out there like me when I started this process - unpack the xlsx file by changing .xlsx extension to .zip, then unzip the zip to a folder since you can't edit files inside the zip folder (you will rezip later)
3) Open up the styles.xml file inside the xl folder using notepad++
3) Control find for "x:" to find instances where x is used as namespace
In my case, I found this:
<x:ext uri="{9260A510-F301-46a8-8635-F512D64BE5F5}" xmlns:x15="http://schemas.microsoft.com/office/spreadsheetml/2010/11/main"> defaultTimelineStyle="TimeSlicerStyleLight1"/></x:ext>
Since there is an x15 after xmlns: I know the name space here should be x15 and not x (according to the microsoft.com link at the beginning of this post)
So the <x:ext... should be change to <x15:ext... and the </x:ext> should be changed to </x15:ext>
4) Make these changes to all instances of x: to the correct namespace and hit save on styles.xml
5) Rezip the excel folder and change .zip to .xlsx
6) Open the file in excel - this worked for me but no guarantee it would work for you
Message me if you have any questions - thanks for the clues
