I was at the Sydney SharePoint user group on Tuesday when the presenter mentioned that you couldn’t update lists using Excel 2007… and in the back of my mind, a thought bubbled up through the primal ooze that too much booze will make of your brain and whispered to me… "I think it can…" 🙂
I remembered reading a blog article about this and struggled to find it, but true to form a Blog post that I flagged in June last year was still flagged in my Google Reader (thank-you Google, where would I be without you).
Sure enough, there’s a free Microsoft add-in for Excel 2007 that allows you to create a list and publish it to WSS 3 / MOSS 2007 (you can’t save it as an XLSX, you still need to store it as an "old-skool" XLS format file, but it’s better than nothing). Here’s the Blog entry in the SharePoint Team blog, here’s the MSDN article that talks about the issue as well as the add-in, and here’s the add-in download. This is all thanks to Jon Adams (a Developer from Microsoft) – Thanks Jon!
There’s also some additional info on how to reattach a linked list if it was saved as an XLSX file type here.
