simple json-decode

simple_JsonDecode.m is a json-file parser written in MATLAB. It reads a json-file and returns the fields as a MATLAB-struct. This script is suited for oder MATLAB versions (<2017) In newer MATLAB versions, the 'jsondecode'-command should be available as a built-in function.
Advantage: No compilation needed!

Usage:

simple_JsonDecode(jsonFilePath) or simple_JsonDecode to open a UI-menu for selecting a json file

Input: jsonFilePath: full path of json file
Output: MATLAB-struct

Assumed format of json-file:

  "FIELDNAME1": DOUBLE,
  "FIELDNAME2": "STRING",
  "FIELDNAME3": [ARRAYVALUE1,ARRAYVALUE2],

Example:

simple_JsonDecode('jsonfile_example.json')

expected output:

ans = 
struct with fields:
