If I had to pick one article from this site that I thought had been the most popular it would probably be this one about exporting to Excel.
Well, that was over two years ago and better methods have come to light. Laurens (AKA Larry Lizzard) has written an excellent article discussing techniques to make large Domino web Views fast and efficient. He's also introduced me to a new way of exporting data to Excel. Called "Web Query Files" (*.iqy) they simply point Excel to an online table of data and pull it all in. Here's an MS "How To" on the subject. What Laurens has done is use them with Domino views. Much like my original article but without the need for any nasty agents.
There's a demo database, from where you can export the whole view to Excel. To do this your browser opens a "file" of content-type text/x-ms-iqy. In Internet Explorer this should open Excel without warning. In Mozilla you will probably be asked what to do with the file. With some playing you can get both browsers to automatically launch Excel.
If you're interested, the .iqy file is simply plain text and looks something like this:

Note that the table used for the view has sortable columns. More on that when I publish Laurens' article in the next day or so...
