    <p>If you want to read from excel in C#, i've used this library with great success, it'll give you the flexibility to parse columns/rows just however you'd like:</p> <ul> <li><a href="http://sourceforge.net/projects/koogra/" rel="nofollow noreferrer">http://sourceforge.net/projects/koogra/</a> (read-only)</li> </ul> <p>Other open source libraries i haven't used but could be good:</p> <ul> <li><a href="http://nexcel.sourceforge.net/" rel="nofollow noreferrer">http://nexcel.sourceforge.net/</a> (read-only)</li> <li><a href="http://npoi.codeplex.com/" rel="nofollow noreferrer">http://npoi.codeplex.com/</a> (can read and write)</li> <li><strike><a href="http://developer.novell.com/wiki/index.php/Poi.Net" rel="nofollow noreferrer">http://developer.novell.com/wiki/index.php/Poi.Net</a></strike> (this project is dead)</li> </ul> <p>Alternatively, you can use one of the many good Java libraries, and convert it into a C# assembly using IKVM:</p> <ul> <li><a href="http://jxls.sourceforge.net/" rel="nofollow noreferrer">http://jxls.sourceforge.net/</a></li> <li><a href="http://www.andykhan.com/jexcelapi/" rel="nofollow noreferrer">http://www.andykhan.com/jexcelapi/</a></li> <li><a href="http://poi.apache.org/" rel="nofollow noreferrer">http://poi.apache.org/</a> (this one's the grand-daddy of java XLS libraries)</li> </ul> <p>I've covered how to do the IKVM Java -> C# conversion here (it's really not as horrible an option as you think):</p> <ul> <li><a href="http://splinter.com.au/blog/?p=207" rel="nofollow noreferrer">http://splinter.com.au/blog/?p=207</a></li> </ul>

    1. COI look forward to trying koogra and nexcel. I'll let you know how they work out for me.

    2. COI've been using koogra for more than a year in a production system parsing half a dozen excel files daily, it really works quite well, however its documentation is nonexistent. Get in touch if you get stuck with it.

    3. CO+1 Chris, POI via IKVM isn't such an unwise option as it first appears. It's a very robust library.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
