How to create random array of string

Hey mockaroo is AWESOME

I want to create array of string

{
 shopNumber : 36, 
 fruitList : ['orange' , 'apple' , 'watermelon']
}

i can create array of object but there is no option for array of string

i tried

fruitList - Json/array
fruitList[0] = 'orange'

not hapenning

Make a field “fruitList” with datatype “Formula”.
In the formula field, set the following value:
[ "orange" , "apple" , "watermelon" ]

this will create the following output:

{
  "shopNumber": 36,
  "fruitList": [
    "orange",
    "apple",
    "watermelon"
  ]
}
