Are you ready for an Excel challenge?
Today, your job is very simple. Just find a pattern in a text and return corresponding value.
In a range we have some resource types & their billing rates.
In another range, we have some descriptions. Each description contains a resource type somewhere inside it. We need to retrieve billing rate for each description by looking up which resource type is mentioned in it.

There are many web pages devoted to Excel Charts and there are many web pages devoted to Creating Dynamic Ranges, but a lot of these suffer when the data is poorly organised or non-contiguous.
Today we look at a Technique for Creating Dynamic Charts with Non-Contiguous Data.Continue »
Today at Formula Forensics, Guest author Sajan shows us how to extract a sorted, unique list of items, displaying the most frequently occurring items first, while restricting the output based on some additional criteria.Continue »
Need to count how many unique values occur in a range?
Learn how to do this and how the formula works right here.
A while ago (well more than 3 years ago), I wrote about an array formula based technique to check if a list of values have any duplicates in them.
Today, lets learn a simpler formula to check if a list has duplicate numbers.
Assuming you have some numbers in a range B4:B10 as shown below, we can use MODE + COUNTIF formulas to check if there are any duplicate values in a list.Continue »
Lykes asked Formula Forensics “How does a formula work?” Lykes has been using the formula without understanding it.

Today we look at a Lykes question.
We love to compare. The instinct to compare leaves no one. Even my two year old twins compare their toys with each other (and fight).
It would make Excel hugely popular if Microsoft builds a handy data comparison tool right in to it. Alas, they have customizable ribbon, 3d effects & equation editor…
Since comparison is one of the main uses of Excel, we have written extensively about it here.
But there is always one more interesting comparison problem. Today, I want to share one such problem, based on a comment left by N-Man.Continue »

Today we pull apart an answer to this question and see how it works.Continue »
Comparison is one of the most common things we do with Excel. Naturally, there are so many ways to compare 2 lists of data using Excel.
Today, I want to share an interesting comparison problem with you.
Lets say you run a small shop which sells some highly specialized products. Now, since your products require quite some training before customers can buy them, you keep track of all product queries and arrange demos.
After a hectic week, you are staring at 2 lists. One with product queries, another with product demos. And you want to know whether all the queries are answered with a demo or not.Continue »
