About me: Hui

Hi. My name is Ian Huitson but everyone, except my Mum, calls me Hui

I work as a Consulting Mining Engineer in Perth, Australia. I have a Bachelor of Engineering Degree (Mining) from the Ballarat College of Advanced Education in Australia.

I am passionate about scheduling and budgeting, simulation and mathematics but more importantly is their application to real world problems.
I have been using spreadsheets since Visicalc and have used Lotus 123, Open Access, Quatro Pro, 20/20 and Excel.

I am a former Microsoft MVP (Excel) having held the award from 2013 to 2019.

I should add that most of my contributions to the Excel community were here at Chandoo.org and at Excel Hero, see below.

Why do I start equations with a =+ ? Because Open Access used to start equations with a + and it has just stuck, although I am getting better at not doing this.

Open Access also had a great function ! which I often wish Excel had. In use you could do something like convert Celsius to Fahrenheit Enter =(9/5)*!+32 into a cell. Then enter say 20 into the same cell and the cell would display 70. The ! took the input directly into the cell and used it in the formula and displayed the answer in the same cell. The cell still has the equation.

I am married to Eva, and have 5 children and 1 grandson. You can see a few wedding snaps here.

In 2009 I took 9 months off work and we did a bit of traveling and during this time I started answering questions on Chandoo’s, newly setup, forums where I have helped out ever since.

In May 2010, Chandoo asked me would I write an article on Monte-Carlo Simulation after I had described the process in a post response. This resulted in the well received Data Tables & Monte Carlo Simulations in Excel a Comprehensive Guide. I have written a further 100+ posts since then as well as Starting and Authoring the Formula Forensics Series.

My favorite post is: Hui’s World and Dynamic Dancing Pendulums

My favorite post by someone else is Lukes: Extract a sub list according to Criteria using Formula

The question most asked of me is: “How do I become great at Excel?

If you really want to learn how to use Excel, my First suggestion is to attach yourself to a Forum and start answering questions and pull apart how other have answered the same question. You will be amazed at how quickly your skills improve. The Chandoo.org Forums are a great community to start in.

I hope you enjoy my contributions below:
