Merry Christmas! I hope you're relaxing today, and spending time with friends and family.
Here's an Excel Christmas tree for you to enjoy, if you have Excel 2007.
The lights on the tree are created with conditional formatting icons, and will change colour if you press the F9 key, to recalculate the worksheet.
You can download the zipped Excel Christmas tree file, and it doesn't contain any macros.
However, the conditional formatting icons will only work in Excel 2007 or later.
