Of all the "Excel" sites I have visited, yours is the most friendly and inviting, that I have come across. -Steve

I am just loving exceljet. Honestly THE best money I ever spent! What is so good about this resource is that it is in short, specific video clips, with both audio and text and with practice downloads for hands-on experience. I like the way you highlight what you are talking about in orange, and it isn’t too fast that the eye can’t see it before you move to the next thing! I love how you provide instructions for the absolute beginner right through to really advanced things. -Anne
