Formula Forensics 013. – On Vacation
Today Formula Forensics takes a vacation.
Formula Forensics is actually on a working vacation today, over at the Excel Hero Academy.
Well technically Formula Forensics has been invited to analyse a formula at the Excel Hero Academy.
If you are a member of the EHA you can see Formula Forensic 013 on the Front page of the Academy, today.
Formula Forensic 013 is the analysis of 3 possible solutions to the first Challenge at the Excel Hero Academy, Yes the Sales Commission challenge.
I can’t publish the solution here as that would spoil it for people who haven’t done it yet or those who plan to attend the Academy later.
But the challenge is ?
You’ll need to join the Excel Hero Academy to find out…
What is this “Excel Hero Academy”?
The Excel Hero Academy is an online training program where Daniel Ferry the owner of the Excel Hero Blog teaches us the techniques he uses on his Excel Hero Blog. If you haven’t seen some of the material at Excel Hero Blog do yourself a favor and keep it in your blog reading list.
Today, here, at Formula Forensics I am going to run through a few of the things that you can learn at the Excel Hero Academy.
Twice a year Daniel opens the door to the Excel Hero Academy. Typically In late Winter and Summer (US seasons). The EHA 3 enrollment has just closed. and the next Academy EHA 4 will open in the Summer (United States summer).
The academy is where Daniel teaches us the techniques he has used throughout the Excel Hero web site to deliver stunning animated charts, business tools and optical illusions. His site is really a showcase for the use of the underlying techniques.
The Academy consists of 12 Modules covering advanced Excel technical skills:
Module 1: Named Formulas
Module 2: Array Formulas and Named Formulas 2
Module 3: Charting 1
Module 4: Dashboards 1
Module 5: Database Techniques
Module 6: Advanced and Creative Formulas
Module 7: Charting 2 with Animation
Module 8: Excel and Access
Module 9: Dashboards 2
Module 10: Classes (VBA on Steroids)
Module 11: Optimization (Speeding up large/slow workbooks)
Module 12: Extreme Excel
So today instead of having a Formula Forensic, I have decided to showcase some of the learnings and techniques that have been picked up and then used on real life problems by Excel Hero Academy students, including myself.
Excel Hero Academy Showcase
Below is a brief showcase of some of the material which has been used with learnings from the Excel Hero Academy here at Chandoo.org
Mod 1. Named Formulas
Using formula: =SUMPRODUCT(MID(B4,ROW(OFFSET($A$1,,,LEN(B4))),1)+0)Refer: http://chandoo.org/wp/2011/03/18/calculating-sum-of-digits-in-a-number/
Mod 2. Array Formulas and Named Formulas 2Batman Symbol Area Chart Consists of 2 Series (upper and lower parts), Sourced from 19 Named Formula, No data is on the worksheet except the Detail parameter. Module 2 Homework, Dan – EHA 3 Student
Mod 3. Charting
Mod 4. Dashboards 1
Mod 5. Database Techniques, Mod 2. Named Formulas & Mod 3. Charting 1http://img.chandoo.org/d/My-Excel-Age-hui.xlsb
Mod 6. Advanced and Creative FormulasQuote: For this homework assignment, I created a very basic spreadsheet that accepts a data table and then allows you to count the number of rows that match a single set of criteria for the specified column. Bob N – EHA 2 Student
Mod 7. Charting 2 with AnimationQuote: “I found this lesson very interesting. I deal with dashboard reports everyday here at work, this technique was new to me. Suprisingly, the formula and the code weren’t terribly complex. I once had an Excel instructor categorize Excel knowledge into three areas: What you know, what you know you don’t know, and what you DON’T know you don’t know. This lesson fell into the latter. This technique will be used quite a bit going forward.” Jay – EHA 2 Student
Mod 9. Dashboards 2
Putting it all together: Array Formulas, Named Formulas, Advanced and Creative Formulas, Charting with Animation
Quote: “I cannot forget the shear amazement and joy when after assembling this, I pressed the Start button and it Worked.” The 3D Dancing Pendulums model – Consists of a Scatter Chart with 18 series derived from 57 Named Formula driving the location calculations. It includes minimal VBA to handle the animation and controls. Author: Hui Refer : http://chandoo.org/wp/2011/07/06/3d-dancing-pendulums/

Formula Forensic will return from vacation next week with our usual line up of Excel formula forensic analysis.
Formula Forensics “The Series”
Formula Forensics is a regular series at Chandoo.org where each week I pull apart a formula as we have done above and see what makes it tick.
You can learn more about how to pull Excel Formulas apart in the following posts
We Need Your Help
Formula Forensics is always looking for new and exciting formulas to pull apart and examine.
A Challenge for EHA students is to find your own formula and examine what makes it tick.
