Variable to string for a non coder

Hi! I’m polling an API that gives 3 letter abbreviations. I have those store on better logic as a variable using the HTTP app to poll.
My issues is that I need to announce it to a senior staying at home and would like to change that variable to a string but I’m not sure how to go about doing it easier.
There are 30 variables and I’m sure there must be some creative ways to convert the variable instead of parsing through 30 flows to get it.
Any idea?

Perhaps you can do something with MQTT or Homey script?
