Project Description

ClosedXML makes it easier for developers to create Excel 2007/2010 files. It provides a nice object oriented way to manipulate the files (similar to VBA) without dealing with the hassles of XML Documents. It can be used by any .NET language like C# and Visual Basic (VB).

Q: Dude, where have you been?

A: I've been making a survey app called Conspek. It's now open to the public. My hope is that it will be able to pay the bills and allow me to keep working on ClosedXML.

Q: Why a survey tool?

A: The same reason I created ClosedXML, I wasn't happy with my options. A while back I had to create a survey but all online survey apps were fiendishly hard, all so clunky, and with a million options in my face (that I would never use). So I created my own survey tool with the goal of making the experience as easy and simple as possible. Try it out and give me some feedback at or better yet, recommend it to someone you know who does surveys ^_^

What can you do with this?

ClosedXML allows you to create Excel 2007/2010 files without the Excel application. The typical example is creating Excel reports on a web server.

If you've ever used the Microsoft Open XML Format SDK you know just how much code you have to write to get the same results as the following 4 lines of code.

            var workbook = new XLWorkbook();
            var worksheet = workbook.Worksheets.Add("Sample Sheet");
            worksheet.Cell("A1").Value = "Hello World!";

Something more elaborate:

The Documentation page has an example of how to create the following table (Showcase) as well as many other examples:
