Malcolm Gladwell’s book Outliers is a great read – I reviewed it here. Its premise is that some outliers (events that are far outside “normal” expectations) have causes and hence are worthy of investigation. Excel have some functions that can help identify outliers in your data.
Recently a client wanted help in summarising a large data list of employees. They wanted to identify the years of service in terms of 5, 10, 15 years and other milestone years based on a start date.
In Excel it is quite common to test a cell for either a zero or a blank. If either of these two entries are found then you do a particular calculation. There is an easy way to handle this.
I recently read a blog post about using Excel for SEO (Search Engine Optimisation). It mentioned a function to extract a domain from a URL. The function was from Google docs, not Excel. So I wrote an Excel formula to extract the domain from their list of URLs.
Rounded values in Excel can pose a few issues. There is a formula you can use that can round a range of values and then SUM the results. This can be used as a check total for rounded values.
Let’s say you have codes that have differing numbers of characters and you need to analyse them based on how many characters a code has. There is one function that can SUM and COUNT based on the number of characters in a code.
Getting dates into order is usually a job for Power Query, but not everyone has it or uses it so I still get requests for formulas to fix text dates.
Excel 2016 has introduced a new type of IF function to simplify handling multiple conditions. It is called IFS.
When creating ranges of formulas that you want to copy down, you sometimes have a trade off in the use of fixed and relative references. If you need to create a relative reference that acts like a fixed reference you can use a trick.
Formatted Tables are great but there is an issue when it comes to copying formula that use the table names (Structured References). There are two techniques that cope with this limitation.
When you create formulas that refer to other sheets Excel typically includes the name of the current sheet when you return to the current sheet and refer to a cell.
We’ve all heard the term “A month of Sundays” to describe a long time. Well what if you wanted to count how many Sundays between two dates?
If you are using date-based headings in your reporting models please consider using dates in the headings rather than text. I’ll explain why.
The NETWORKDAYS.INTL function was added in Excel 2010. It allows to calculate how may work days between two dates using non-standard weekends. Some countries don’t have Saturday/Sunday weekends.
I had a question during one of my Date and Times Webinars in February. It was about months and fortnights. I couldn’t answer it during the webinar, but I did follow up with an email with the solution. The answer follows.
Most people are unaware that the SUMIFS function has a serious limitation when it comes to codes with leading zeroes. This post shows you how to perform calculations involving codes with leading zeroes. This issue also affects SUMIF, COUNTIF and COUNTIFS.
I had a question on another post on how to convert Nov 21, 2014 into a date Excel recognises. The solution involves six functions working together.
If you need to convert a number into a text number within a formula there are a couple of ways to achieve this, but one way is a lot easier.
Let’s say you have a table of codes and every month there are a few you want to check out. You could use a VLOOKUP to extract all the details for each code, but let’s say you want to view the codes in the table.
I wanted to offer a solution to a common problem I see in Excel. It relates to creating totals in data that isn’t structured that well.
