Today we look at a very neat way of doing a complex Nested If or Vlookup style problem with a simple but beautiful Sumproduct based formula.

Lykes asked Formula Forensics “How does a formula work?” Lykes has been using the formula without understanding it.
The formula counts how many times the letters from a list of letters occur in a list of words.
Today we look at a Lykes question.

Count How Many Times a List of Values Occurs in a Range
(or How Can I Simplify My Formula)

Today in Formula Forensics we look at how to count how many times a range of values occurs within a Range of cells and in the process simplify a very nasty formula.

In the past here at Chandoo.org and at many many other sites, people have asked the question
“How can I display a number multiplied or divided by 10, 100, 1000, 1000000 etc, but still have the cell maintain the original number for use in subsequent calculations”.

Typically the answer has been limited to “It can’t be done” or “it can only be done in multiples of 1000”.

This post will show you how you can display numbers whilst Dividing or Multiplying the cells value by any Power of 10 !

Houston, We’ve Had a Problem!
In the initial emails requesting a solution to yesterday’s Formula Forensics, Chandoo’s solution, although Technically correct, Didn’t work ?
This post looks at the problem and what was wrong with the data causing the error.

Today in Formula Forensics we look at how to Calculate the Maximum value from a list subject to other fields meeting certain criteria:

A common Forum Post question and one that Chandoo has written about a few times is, Does my data overlap with another range?

This week Formula Forensics examines Pradhishnair’s Overlapping Chaninage Problem where he wants to know if two values overlap with a range of other values

One of the most asked questions within the posts and Forums at Chandoo.org is, How Does Sumproduct work ?

Today in Formula Forensics we take at look at just that with a few worked examples.

Palindrome: – A palindrome is a word, phrase, number, or other sequence of units that can be read the same way in either direction, with general allowances for adjustments to punctuation and word dividers (“Wikipedia”).

This week in Formula Forensics we’re having a look at determining if a cell contains a palindrome.

Zebra Stripes and Checker Boards

This week in Formula Forensics I’m taking a break from Array Formulas to have a look at some Zebra Stripes and Checker Boards.

No, I haven’t gone crazy, although some may argue that point.

More specifically were going to take a look at, Zebra Stripes and Checker-Board Conditional Formatting.

Congratulations Chandoo.org on reaching 1,000,000 page hits in November 2011.

This is the Forth post in Chandoo’s, Formula Forensics series.

Last week Luke showed us how to extract a sorted list according to a criteria from a larger list
and he analysed a formula to solve this problem

This week we look at Fred’s Problem…

How do I simplify a very long formula?

Maintenance on the 18 month old, Data Tables, Monte-Carlo Simulations and Fractals in Excel – A Comprehensive Guide has been completed.

Formula Forensics # 002 – Joyces Question

This is the second post of a new regular weekly series at Chanoo.org, Formula Forensics, where we will examine how a formula works from the inside out with a worked example to help you understand its formation.

Last week we looked at Taruns problem and analysed a formula to solve his problem

This week we look at Joyce’s Problem…

Normally when responding to a Post or a Forum Post you will see a plain old text response like

Occasionally you may see some Bold or Code highlighted like

How is this done and what else can I do to add value / pizazz to my posts ?
