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.
