To generate a random password in Excel, you can use a combination of Excel functions to ensure the password is both secure and unique. Below, I'll guide you step-by-step on how to do this, including creating passwords that meet typical security requirements such as including uppercase and lowercase letters, numbers, and special characters.

Generate random passwords with formulas

Formula Explanation:
  • CHAR(RANDBETWEEN(65,90)) generates a random uppercase letter;
  • CHAR(RANDBETWEEN(97,122)) generates a random lowercase letter;
  • CHAR(RANDBETWEEN(48,57)) generates a random number between 0 and 9;
  • CHAR(RANDBETWEEN(33,47)), CHAR(RANDBETWEEN(58,64)) generate random special characters, (such as: @,:,!...)

Notes: Improvements and Customization

  • Length: Adjust the length by adding or removing concatenated parts.
  • Character Set: Modify the RANDBETWEEN() functions to include different or additional special characters.
  • Randomness: Each time the sheet recalculates, the password will change. To prevent this, copy the generated password and paste it as values elsewhere in your sheet.
