Since 2004, I've been participating in various online forums, where I enjoy helping others with Microsoft Excel and VBA.

In 2009, Microsoft gave me my first MVP award in recognition for my online contribution to the Excel community. And I continued to receive the award each year until 2016.

Special Acknowledgement

Over the years, I've learned so much from Aladin Akyurek, a long time member of the online forum at MrExcel. In my humble opinion, he's truly an Excel guru.

Whenever I try to come up with a formula solution, I always try to follow the three basic principles that he taught me: correctness; robustness; and efficiency.

Thank you Aladin for sharing your expertise with us!
