Hello so i tried to use API to retrieve a test customer and converted into valid json format but the json it shows me was invalid as well as the data it shows me was invalid/hard to read so is there any way you guys can clean it off a bit or give me an example code to help me?

i just directly print out custom using print_r function and the data below is what it returned
