Hi Pedro, thank you for this component it was very useful for my 1st full project as a trainee!
I discovered a small problem with the css though and thought I should share how I fixed it!
As you can see in these screen shots - https://imgur.com/a/vME2Vpn - one of the strings was too long for the screen, it didn't wrap well.
I added the following property:

.json-string {
  color: #0B7500;
  white-space: normal;
}

It was a quick fix you might want to implement :)
