Answer 1

Let's say you want to substitute something in an array of string and you don't want to perform the copy-paste on your entire sheet.

Let's take this as an example:

• String array in column "A": {apple, banana, orange, ..., avocado}
• You want to substitute the char of "a" to "x" to have: {xpple, bxnxnx, orxnge, ..., xvocado}

To apply this formula on the entire column (array) in a clean an elegant way, you can do:

=ARRAYFORMULA(SUBSTITUE(A:A, "a", "x"))

It works for 2D-arrays as well, let's say:

=ARRAYFORMULA(SUBSTITUE(A2:D83, "a", "x"))
