Is there a way to convert a text list with /n (new line) to a string list for Terraform?

I have a file that has a list of strings, separated by a new line.

10.0.0.0
10.0.0.1
10.0.0.2

I would like to convert them into a List of type String, so that I can utilize them within my Terraform.

Is there a way to do this?

I can save the file as whatever format I like. I have been trying to save it as a yaml, then utilize yamldecode to make this convertion to ['10.0.0.0', '10.0.0.1', '10.0.0.2'] but so far, I haven't been able to.

Is there a way to achieve this?

Any help on this would be appreciated!

You can do something like this:

locals {
  lines = [for line in split("\n", file("file.txt")): chomp(line)]
}

This will split the input based on newline (\n) characters. chomp will remove \r characters in case your file is using CLRF endings (if you are using Windows).
