Array Syntax Custom Function

Array syntax is a powerful feature in Excel. Array syntax allows you to create a list within your formulas which makes them self-contained. Typing array syntax is difficult as you need to use a combination of quotation marks, commas or semi-colons plus braces (curly brackets).

Padding Entries in Excel

Another post inspired by the book 101 Ready-to-Use Excel Formulas by Michael Alexander and Dick Kusleika. This one is Formula #22 and covers padding entries with zeroes.

Significant Digits in Excel

This post is inspired by the book 101 Ready-to-Use Excel Formulas by Michael Alexander and Dick Kusleika. Formula #10 allows rounding to a certain number of significant digits. This post shows how to convert that formula into a custom function.

Does an Excel range contain sequential numbers?

I have created a custom function to check if a range has sequential numbers. The range doesn’t have to be sorted.

Excel Sheet Names and Emojis

Did you know you can use Emojis on the sheet tabs? The font on sheet tabs is small, so some emojis may not be that effective, but simple emojis can be.

A Better SEARCH Function for Excel

The SEARCH function has a couple of issues that make it difficult to use. This makes it a prime candidate for a custom function to fix its limitations.

Excel Custom Function for a List

Excel’s Custom Lists are great, but you need to drag them to create them. If you have a list that you use frequently why not create a custom function to display it? This has the added advantage of creating a spill range that can then drive other dynamic array formulas.

Calculating YTD percentages in Excel

When working with YTD percentages you must be careful with the calculation. Adding up values or amounts is easy. Working with YTD percentages require a bit more work.

Custom Function to Reverse a String in Excel

When I started learning Python, I saw it had a Reverse function and thought, “I could do that in Excel.”

Using the Custom Month List Function

In the previous post I created a custom function that creates a horizontal list of months based on three inputs. In this post I share a few ways that you can use this list.

Excel Month List Custom Function

It is common in reporting files, budgeting and forecasting files to create a list of months going across the page. The custom function in this post can automate the process.

Excel and Ordinals

A recent update to Excel included ordinals as an option when you drag with the fill handle. A few months back I made a post about a Custom function for ordinals in dates. Dates are a bit easier because they max out at 31. I thought I would extend the function so that it handled all numbers.

Fixing the UNIQUE Function

The UNIQUE function in Excel has a problem when it comes to handling blank cells. Blank cells are treated as zero and if you have a blank cell and a zero in a range then UNIQUE will return two zeros. Also, if a cell has a function that returns a blank cell, then that is treated differently than a blank cell. Let’s create a custom function to fix UNIQUE’s blank cell blind spot.

Convert Day Text into Day Number in Excel

Excel uses a number from 1 to 7 to refer to the days of the week. The WEEKDAY function returns the number based on a date. Excel doesn’t a have a function to return the day number based on a text day like Monday. Time for a custom function.

Custom Function to Count Specific Characters in Excel

I have previously covered a formula that counts specific characters. Since it used multiple functions, I thought I would simplify it by creating a custom function.

Benford’s Law in Excel – Part Two

Benford’s law is used in auditing to identify data sets that may have been manipulated or adjusted. In my previous post I created a report to analyse a data set based on Benford’s Law. In this post we will create a single formula to create the report and then convert that into a custom function.

Benford’s Law in Excel – Part One

Benford’s law is used in auditing to identify data sets that may have been manipulated or adjusted. In actual data sets when reviewing values the 1st digit of the values tends to follow a predetermined frequency. For example, roughly 30% of the values should start with a 1.

SUBTOTAL and Dynamic Arrays in Excel – Part 3

The SUBTOTAL function in Excel is quite flexible. The single function allows you to perform 11 different calculations. In this post we will create a custom function to summarise a data set.

Excel Custom Function to Return Unique Random Whole Numbers

In last week’s blog post I covered a complex formula to return unique random whole numbers. In this weeks’ post we will look at how we can convert that complex formula into a custom function.

Custom Calendar Function in Excel

A few years back I posted a series of three posts about developing a formula to create a month calendar in Excel. I thought I would revisit that and convert that long formula into a custom function using LAMBDA.

TEXTBETWEEN function in Excel

Excel has new TEXTBEFORE and TEXTAFTER functions. It doesn’t have a TEXTBETWEEN function.  Let’s make one.

Custom Function for Age in Excel

Calculating age with years months and days takes several functions to create. Whenever you need multiple functions to calculate an entry you may have a good use case for a custom function.

Custom Function for Days in the Month

Excel’s EOMONTH function is great. Here is a tweak using a custom function to calculate the number of days in a month.
