If your formula returns a #VALUE! error, you may have an invalid number as an argument to the CHAR function. Why does my formula return a value error?.If we use the formula =CHAR(33), we will output an exclamation point. For example, the formula =UNICODE(“!”) returns the value 33. How do I know what numbers to use for a particular character?Įxcel has a built-in function called UNICODE that can return the number that corresponds to a specified character.We can use different ranges to create a mix of lowercase letters, uppercase letters and numbers.Next, we’ll repeat the same process and concatenate both results using the ampersand symbol ‘&’.

To pick uppercase characters, we’ll use the range 65 to 90. For this example, we want to first output a random uppercase letter. Since the CHAR function should have a random integer as an argument, we’ll have to use the RANDBETWEEN function.Next, we simply type the equal sign ‘ = ‘ to begin the function, followed by ‘ CHAR( ‘.In this example, we’ll be outputting our password in cell B1. First, let’s select the cell that will hold our generated password.You’ll learn how we can use the CHAR and RANDBETWEEN functions to create a string composed of randomly selected characters automatically.

How to Quickly Generate Random Password in Excel If you’re ready to try setting up your own password generator in Excel, read the next section to follow our step-by-step guide. You can make your own copy of the spreadsheet above using the link attached below. One limitation to this method is that the string will always be a fixed length. To create our final password, we simply concatenate multiple instances of the CHAR function.

For example, the formula =CHAR(RANDBETWEEN(97, 122) can return any lowercase letter. We use the RANDBETWEEN function to choose a random integer in a specified range. This means that =CHAR(65) will return an ‘A’. For example, the uppercase letters from ‘A’ to ‘Z’ are in the range 65 to 90. The CHAR function accepts an integer value as an argument and outputs the corresponding Unicode character. To get the values in Column A, we just had to use the following formula: =CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(97,122))&CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(97,122))&CHAR(RANDBETWEEN(65,90)) The last column introduces special characters such as ‘+’ and ‘*’ to add even more security. The second column generates alphanumeric passwords. The first column creates a five character long string composed of only letters. In the example below, we have three columns with different types of generated passwords. Let’s take a look at a real example of a spreadsheet that can quickly generate a secure password in Microsoft Excel Since we now know when it’s useful to create random passwords in Excel, let’s take a look at a sample spreadsheet that uses a formula to generate them.Ī Real Example of Quickly Generate Random Password in Excel We can similarly use the same technique to create random PIN codes of arbitrary length. The CHAR function and RANDBETWEEN function will help us randomly pick letters, numbers, and symbols. The trick to create the randomized string is to build it one character at a time. For example, we could indicate that we want the first 5 characters to be letters, the next two to be numeric, and the last character being either a ‘!’ or a ‘?’. We can use Excel to quickly generate a list of random passwords of a specified length. You plan on giving each of these files a randomly generated password before sending.

zip files that you would like to send out via email. Let’s take a look at a use case where you might have to generate several secure passwords at once. For example, the password ‘dQw4w9WgXcQ!’ is more secure than ‘qwerty123’.
