Advanced Uses of the RANDARRAY Formula in Excel

As an Excel fan, I’m always searching for new and thrilling formulae. The RANDARRAY formula caught my eye. It can conveniently generate random numbers. But do you know it can do more? Let’s explore some advanced uses of the RANDARRAY formula in Excel. In the following subsections, I’ll show you how to generate random dates, letters, and even words with it. Get ready to level up your Excel abilities!

Generating Random Dates using RANDARRAY

Excel may display random numbers instead of dates. To fix this, select cells and press “CTRL+1”. Then select “Date” under “Type”.

You can also use the “&” operator to generate random dates. For example: “=RANDARRAY(10)*50+DATE(2022,1,1)” adds 50 random days to January 1st, 2022.

Pro Tip: Easily remember dates with named ranges. Highlight a cell with a date and go to “Formulas” -> “Define Name”. Give it a name and use it in formulas later.

Generate random letters using the RANDARRAY formula. Just use the array-formula “{=CHAR(RIGHT(LEFT(UPPER(CODE(RANDARRAY(1,10,65,90)))),1)+ROUNDUP(RANDARRAY(1,10)*25,)}”. This generates ten uppercase random letters.

Generating Random Letters using RANDARRAY formula

Generating random letters using the RANDARRAY formula in Excel is easy! Follow these steps:

1. Open a new or existing spreadsheet.
2. Choose a cell to put the random letter.
3. Type in the formula: “=CHAR(RANDARRAY(1,1,65,90))”.
4. Press enter.
5. You’ll now see a random letter.
6. To generate more, drag the formula down or to the right.

Using the RANDARRAY formula can be powerful. We use CHAR and ASCII to manipulate the output of RANDARRAY.

In this case, we want to generate a single number between 65 and 90 – the ASCII codes for uppercase letters. CHAR then converts the number into a randomized letter. This is useful for passwords, sorting algorithms, or other situations where randomized letters are needed.

Try this method for generating random letters in Excel. Change the parameters and see the results!

Next, let’s explore how to generate entire words using the same method but with added formulas and functions.

Generating Random Words using RANDARRAY formula

RANDARRAY is a must-have skill in Excel! It’s useful to generate random data for tests, educational tasks and fun activities. To use it, make a list of words. Then use INDEX with RANDBETWEEN to select one randomly. For example, if there are 10 words in cells A1 to A10. Use: =INDEX($A$1:$A$10,RANDBETWEEN(1,10))

Another way: use CHOOSE with RANDBETWEEN. If there’s a list of 5 names in A1 to A5, enter: =CHOOSE(RANDBETWEEN(1,5),A1,A2,A3,A4,A5). This will give you a random word every time!
