=CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(65,90))

This formula generates a random uppercase letter for each position in the string. By copying and pasting the formula into multiple cells, users can generate a series of unique random strings for various purposes, such as generating temporary passwords or unique IDs.

4. Generate Random Uppercase Letter

=RANDBETWEEN(100000,900000)

7. Generate Random Symbol String

=CHAR(RANDBETWEEN(33,47))

This formula will randomly generate one of the following specific characters: !”#$%&'()*+,-./

We talked that the CHAR function will generate lots of specific characters, and if you just want to create a password that can be type on the keyboard, so you should keep the specific character simple and avoid to use characters like ¶, Œ, or ©.

8. Conclusion

Generating random passwords in Excel can be a quick and convenient way to create secure and unique passwords for various purposes.
