Efficiently Read JSON and Create DataFrame

[JesperMartinsson]

I had a similar challenge. Perhaps you can use a sink function and maybe this thread may provide some help:

JSON3 to mutable Dict{String,Any}

I’m using JSON3 to parse an input that can be either a json or an array of json string. I want to convert the output of JSON3.read to either a mutable Dict{String,Any} or Array{Dict{String,Any}}, respectively. I see that copy(JSON3.read(...)) always returns keys as Symbol and not String. The only solution I have so far to return keys as String is to using a sink argument that is a union: JSON3.read(input,Union{Dict{String,Any},Array{Dict{String,Any}}}). Anyone know of a preferred way to do this…
