JSON3 string to Numeric

General Usage

I have this API that returns all data as string:

{
      value: "35.2"
}

Yet I want to map it to astruct with the proper type

struct Data
    vaue::Float16
end

How can I instruct JSON3 to do the conversion?

Welcome Olivier,

You can put your code between double " ``` " to make it more readable.

You can convert it yourself :

input = JSON3.read(string_api) #you can add your relative path with "." notation i.e. JSON3.read(string_api).value

struct Data
  value::Float16
end

#You can convert your input with "parse" function

output = Data(parse(Float16, input))

From the example in the docs:

using JSON3, StructTypes

j="""{"value": "35.2"}"""

struct Data
    value::Float16
end
StructTypes.StructType(::Type{Data}) = StructTypes.Struct()

d=JSON3.read(j, Data; parsequoted=true)
