I can use webread to parse json delivered by a webservice into a struct, but is there any way to do that same parsing if I have the JSON data in a string?

在 MATLAB Online 中打开

This can be done using :

jsondecode('string text');

For more reference:

https://in.mathworks.com/help/matlab/ref/jsondecode.html

Sample program:

myStruct=struct();
myStruct.name="Hello";
myStruct.age="21";
myStructString=jsonencode(myStruct);
fprintf("Original structure: \n");
disp(myStruct);
fprintf("Original structure converted to string: \n");
disp(myStructString);
myStruct2=struct();
myStruct2=jsondecode(myStructString);
fprintf("\n\nOriginal structure parsed back from string: \n");
disp(myStruct2);
