The UNIQUE function has a bit of an issue with blank cells, formulas that return blank cells and zeroes.
If you need a logical test to determine if a list is unique you can use the MODE function with the ISNA function.
If you have a list of numbers that are a text numbers or a combination of text numbers with real numbers there is a technique I covered in this blog post to add them up. But if the range also contains text then the technique won’t work. There is the work around. The solutions below work in the subscription version of Excel. Check the comments section below for a solution for all versions.
One reason I like the N function is because it is Excel’s shortest function name. But it has quite a few useful features as well.
A while back I posted a formula to find the row number of the last used cell in a column. I revisit the solution to provide the last used column number in a row.
I wrote a blog post a while back about outliers and Excel and I thought I would revisit it thanks to dynamic arrays.
If you need to convert between different measurement systems Excel has just the function for you, called CONVERT.
Let’s say you are transitioning to retirement (lucky you) and you only work four days a week. You have Wednesdays off to play golf. You may still do projects and you need to figure out completion dates based on a start date and working days. Excel can help you.
I was recently helping someone with a budget which they had built vertically, with the months going down the sheet. They then asked to display it horizontally, with the months going across the page. In the latest version of Excel this is straightforward.
I wrote an article years ago explaining how to use a related table to handle financial years in Excel Pivot Tables. You can read the article here. If you only want the months in financial year order you can just add an extra column to your table.
I recently downloaded an example file for an Excel challenge. The challenge had a lot of things to do but they were all based on a Timestamp column that had text instead of times.
On LinkedIn recently someone posted an Excel formula solution lamenting that it was long and complex. That of course was a challenge to me to simplify it.
20 years ago my last article for the Accountants Weekly magazine was published. They spelled my name wrong after getting it right for all the other articles, maybe that’s why I stopped.
My second article in Accountants Weekly was published 20 years ago today and it was Top 10 Functions for Accountants.
If you need to add time to an existing time then you need to learn about the TIME function.
If you have a list of first names and last names and you want to make sure the list has no duplicates you can use a formula to confirm the names are unique.
When creating an input range you may need to validate input cells. That may mean ensuring all input cells have an entry. Here’s how.
The Australian Financial Year has its challenges. Working out the Quarter number based on a date has a few solutions. Here’s another one.
In a financial model you often have different types of allocations that start at different times. Creating a short formula to handle this flexibility can be a challenge. Here is one solution.
In Excel your goal should be to have a single formula in a table column that can be copied down the whole column.
When you protect a sheet in Excel many icons are turned off (greyed out), including the ever popular AutoSum icon. That’s when it pays to know keyboard shortcuts.
Let’s say you are getting inputs you can’t control and in some cases you get text and others you get numbers. You want the numbers, but you need to treat text as zero. Here’s the easy way to do that.
In budgets, forecasts, financial models and even reporting models repeating the numbers 1 to 12 can be useful. The SEQUENCE and MOD functions can make it easy and scalable.
Let’s say we need to put a prefix in front of a number to identify the period being used. Whether that be year, month or week.
If you need to confirm a number is a whole number you can use a function with a short name.
If you have the subscription version of Excel you may have the new LET function. This function lets you capture variables within a formula. Let’s see an example.
Many things that were hard or complex are now much simpler. Creating dynamic drop down lists based on previous selections used to be tricky in Excel. Dynamic arrays make it straightforward.
The SUMPRODUCT function has been my favourite function for about 20 years. It is so flexible. Soon it will be redundant thanks to dynamic arrays.
It is best practice to use grouping to hide and unhide rows in Excel. I recently saw a technique that also displays a message.
A few years ago I wrote an article on extracting the end of quarter date from a date. I recently had a query that was related and I tweaked the previous solution to solve it.
