A unique use case for summing values, could be to sum formulas only in Excel.
The SUM function will sum all numeric values in a given range, but you may have a range interspersed with other formulas that calculate subtotals or perform conditional calculations.
So, how do you only sum the cells that contain formulas. Let’s find out.
There are a few methods to calculate age in Excel using formulas. In this tutorial, we will explain how to calculate age in Excel in years from a date of birth.
The formulas detailed can be used to return the difference between two specified dates for other reasons, such as length of service at an organisation, or the difference between two business transaction dates.

Let’s get straight into this. The easiest way to calculate age in Excel is to use the method shown in this shorts video. It uses the TRUNC and YEARFRAC functions in a simple age formula.
The formula returns the difference between the date of birth and the current date in years.
=TRUNC(YEARFRAC(C3,TODAY(),1))
The XLOOKUP function in Excel does not perform a case sensitive match by default. So, the values “London”, “LONDON”, and “london” would all result in a match with the XLOOKUP function.
So, how do you perform a case sensitive XLOOKUP formula?
Let’s find out. Read on or watch the video tutorial.
In this example, the XLOOKUP function is returning the first matching value for the status of each individual and the [Status] in tblRates. The corresponding [Rate] is then returned by the formula.
This XLOOKUP formula is ignoring case when matching the lookup value to the text in the lookup array. This is best demonstrated by the incorrect rate returned for “Sally” in cell D4.
The formula has matched the status of “Sally” to the upper case status value from tblRates. However, we require an exact match on the lower case value found in row 4 of tblRates. The correct rate returned for “Sally” should be 350.
When using formulas in tabular data in Excel, you will need to copy a formula down the entire column, so that each row has that same formula.
There are a few techniques to copying formulas in Excel, and this article will detail what you should be aware of, and why you would apply each specific technique.

Excel stores dates as whole numbers known as serial numbers. Each day, one is added to the serial number of the previous date.
For example, the Excel date, or serial number, for the 1st May 2023 is 45047.
