Calculate Days Open

Explanation In this example, the goal is to calculate the number of days a ticket/case/issue has been open. We start counting on the date a ticket was opened and stop counting on the date a ticket was closed. If there is no closed date, the ticket is still open. Because dates in Excel are just serial numbers , the math is quite simple. We can simply subtract the “Opened” date from the date today, which we calculate with the TODAY function....

Expanding Reference

An expanding reference (or expanding range) in Excel defines a range that expands as a formula is copied down or across cells. This is done by “mixing” absolute and relative references – making the first cell an absolute reference and the last cell a relative reference . Example In the example shown the formula in D4 is: =SUM($C$4:C4) As this formula is copied down column D, it changes as follows:...

Get Fiscal Quarter From Date

Explanation The choose function uses the first argument to “select” remaining elements. For example, in a scheme where 1 = small, 2 = medium, and 3 = large, this formula will “map” the number 2 to “medium”. =CHOOSE(2,"small","medium","large") In the case of fiscal quarters, we can use this same idea to map any incoming month (1-12) to one of 4 quarter values. We just need to use the MONTH function to get the month number as the first argument, then provide 12 numbers (one for each month of the year) that are carefully ordered to reflect the fiscal year desired:...

How To Fix The #Null! Error

Explanation The #NULL! error is quite rare in Excel, and is usually the result of a typo where a space character is used instead of a comma (,) or colon (:) between two cell references. Technically, the space character is the “range intersect” operator and the #NULL! error is reporting that the two ranges do not intersect. This is baffling to the average user but in most cases replacing the space with a comma or colon as needed will fix the problem....

How To Use The Rept Function To Repeat Things

Transcript In this video we’ll look at how to use the REPT function in Excel to repeat text. Excel contains a special function for repeating text named REPT which stands for “repeat.” The REPT function takes two arguments: the text to repeat, and the number of times to repeat the text. So, if I enter an upper case “A” and the number “3,” we’ll get a triple A. If I expose these arguments on the worksheet, I can quickly add a few more examples....

Max If Criteria Match

Explanation The example shown contains almost 10,000 rows of data. The data represents temperature readings taken every 2 minutes over a period of days. For any given date (provided in cell H7), we want to get the maximum temperature on that date. Inside the IF function , logical test is entered as B5:B9391=H7. Because we’re comparing the value in H7 against a range of cells (an array), the result will be an array of results, where each item in the array is either TRUE or FALSE....
