My question is the following: Is there function that does this? Something like flatten_dict(dict, sep="."), or would I have to solve this manually by looping through my nested data? I looked trough the JSON.jl package but either there is no such thing or I missed it.
I am not sure if there is something that fits your exact need, but it does not seem something so hard to implement.
function rec_flatten_dict(d, prefix_delim = ".")
new_d = empty(d)
for (key, value) in pairs(d)
if isa(value, Dict)
flattened_value = rec_flatten_dict(value, prefix_delim)
for (ikey, ivalue) in pairs(flattened_value)
new_d["$key.$ikey"] = ivalue
new_d[key] = value
Creates some intermediary structs, so it is not a solution with the greatest performance, but it does the job.
