The RANDARRAY function takes five arguments, none of which are required: rows, columns, min, max, and integer. By default, rows, columns, and max default to 1, while min defaults to zero and integer defaults to FALSE. Without any arguments, RANDARRAY will return a decimal value between 0 and 1: Use rows and columns to control the number of values returned: Use min and max to set a lower and upper threshold for values. For example, to generate 3 random decimal values in rows between 1 and 5: Set integers to TRUE to return whole numbers. For example, to generate 3 random whole numbers in rows between 1 and 100:

### Examples

In the example shown, RANDARRAY is used to generate 50 values in a range of 10 rows by 5 columns. The formula in B4 is: To return a random array of integers, 5 rows by 2 columns, between 1 and 10, you can use a formula like this:

### Random text

To generate a random letter between A-Z you can use the CHAR function with RANDARRAY: You can also generate random text strings with RANDARRAY.

### Random dates

To generate 5 random dates in the next year, you can use a formula that combines RANDARRAY with the EDATE and TODAY functions:
