Random text values

Excel formula: Random text values
Generic formula 
=CHOOSE(RANDBETWEEN(1,3),"Value1","Value2","Value3")
Explanation 

To quickly fill a range of cells with random text values, you can use a formula based on the CHOOSE and RANDBETWEEN functions.

In the example shown, the formula in C5 is:

=CHOOSE(RANDBETWEEN(1,4),"Red","Blue","Green","Pink")

Which returns a random color from the values provided.

How this formula works

The CHOOSE function provides the framework for this formula. Choose takes a single numeric value as its first argument (index_number), and uses this number to select and return one of the values provides as subsequent arguments, based on their numeric index.

In this case, we are using four values: Red, Blue, Green, and Pink, so we need to give CHOOSE a number between 1 and 4.

To generate this number, we use RANDBETWEEN, a function that returns a random integer between a bottom and top value. Since we are only working with 4 values in CHOOSE, we supply 1 for the bottom number and 4 for the top number.

When this formula is copied down, it will return one of the four colors.

Note that RANDBETWEEN will calculate a new value whenever the worksheet is changed. Once you have values in the range, you may want to replace the formulas with values to prevent further changes.
