# Random number between two numbers

=RANDBETWEEN(lower,upper)

To generate a random number between two numbers, you can use the RANDBETWEEN function. In the example shown, the formula in B5 is:

=RANDBETWEEN(1,100)

The Excel RANDBETWEEN function returns a random integer between given numbers. RANDBETWEEN is a volatile function recalculates when a worksheet is opened or changed.

In the example shown, the formula in B5 is:

=RANDBETWEEN(1,100)

This formula is then copied down from B5 to B11. The result is random numbers between 1-100.

Note that the RANDBETWEEN function will generate new numbers whenever a change is triggered on the worksheet. That includes any edits to the worksheet, also also simply opening the workbook.

To prevent random numbers from being recalculated again, you can replace the formulas with the values last calculated:

- Copy the formulas
- Use Paste Special > Values

### Notes

- The RAND function can generate random decimal values.
- The RANDARRAY function (new in Excel 365) can generate random numeric arrays.
