MATLAB provides jsondecode function to parse JSON into MATLAB structures and then access specific elements similar to how you reference Excel cells. Kindly follow below mentioned steps to parse JSON in MATLAB:
- Read JSON file as a string using fileread
- Decode the JSON structure using jsondecode
- Access the required fields using structure indexing.
Example:
Consider you have a JSON file (data.json):
{
"A": {"a": 100, "b": 200},
"B": {"a": "Hello", "b": "World"}
}
This file can be read and extracted like shown below:
jsonStr = fileread('data.json');
data = jsondecode(jsonStr);
% Access specific data (like Excel cells A1, B2, etc.)
column = 'A';
row = 'a';
value = data.(column).(row); % Access "A.a" (100)
disp(value); % Output: 100
Please ensure that the fieldnames in JSON structure are valid MATLAB identifiers as mentioned in this documentation:
I hope this helps achieve the functionality you desired.
