The website is well-regarded and has been voted as one of the top Excel websites worldwide.

Although highly active in Excel since 1986, Liam was awarded the prestigious Microsoft Most Valuable Professional in Excel only since 2012, due to employment restrictions.  This is a distinction he has won every year since!  The Microsoft MVP Award recognises exceptional technical community leaders from around the world who voluntarily share their high quality, real world expertise with others.  In Microsoft's words, "MVPs are a highly select group of experts representing technology's best and brightest who share a deep commitment to community and a willingness to help others."  Worldwide, there are over 100 million participants in technical communities; of these participants, there are fewer than 4000 active Microsoft MVPs.  Of this pool of MVPs, approximately 100 hold the distinction of MVP-Excel globally.

 Businesses succeed by measured trial and error. Working with businesses for over three decades, I’ve realised it’s only when companies become totally risk averse and daren’t make mistakes that they truly make irrecoverable errors. You have to keep trying things out – you must never stop learning. And Excel’s a great tool for that.
