I think the challenge is to take smaller steps here...

Either solve this challenge by finding a JSON parser and using it, or
redefine the challenge to "create a simple parser".

Parsing JSON is a challenge, but I think you should define an interim
challenge first - one that's less challenging.

Strictly speaking the challenge of parsing JSON in Erlang (and
therefore being able to generate other forms) is not that challenging
as there are like half a dozen decent libraries to do that already. It
can be a challenge to find them, compile and use them - but not that
challenging. So why not just do that and cross this challenge off your
list?

Then, create a new challenge, which is to parse some simply expression
like "1 + 1" into a term in Erlang. You can then do something
interesting with that term! See hint [1]

This is a good challenge IMO because you'll learn a lot about Erlang
(your goal) and you'll also experience the empowerment of building
your own language, even if a very simple one.

What I'm really trying to say is that it's challenging to define the
right challenge. Richard said it best:

But don't criticize mine :)
