Yes, Microsoft Excel has a built-in function that can generate random alphanumeric strings. The function is called

Formula:

RANDARRAY 


and it can be used in combination with other functions to create the desired string.

Here's how you can use the

Formula:

RANDARRAY 


function to generate a random alphanumeric string:

1. Open a new Excel worksheet and select a cell where you want to generate the string.
2. In the formula bar, type the following formula:
   Formula:

   =CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(48,57))&CHAR(RANDBETWEEN(48,57))&CHAR(RANDBETWEEN(97,122))&CHAR(RANDBETWEEN(97,122)) 

3. Press Enter to generate the random alphanumeric string.

The above formula generates a string that contains two uppercase letters, two digits, and two lowercase letters. You can modify the formula to generate a string of different length or with different combinations of characters.

Note that the

Formula:

RANDARRAY 


function is only available in newer versions of Excel, such as Excel 365. If you're using an older version of Excel, you can use the

Formula:

RANDBETWEEN 


function to generate random numbers and the

Formula:

CHAR 


function to convert them to characters.
