[erlang-questions] Want to convert tuple format into map

[Jesper Louis Andersen]

The tools you need are recursion and pattern matching.

Build a set of functions which match on your tuples, uses recursion to
compute subtuples into maps, and then builds a map out of the results at
this level. Suppose we have

T = {x, {data, 34, 35}, {data, 21, 22}},

We can then write a tool

conv({x, L, R}) -> #{ type => x, left => conv(L), right => conv(R) };
conv({data, V1, V2}) -> #{ type => data, value1 => V1, value2 => V2 }.

which can do the conversion by calling itself recursively. These ideas
should be applicable to your case as well.
