is there any way to append multiple json files into single files

I have generated multiple JSON files and want to append these files into one file. Is there a way to merge multiple JSON files into a single file in MATLAB?

Hi Anuj,

You can use below script to append multiple JSON files into single file.

%Read contents of File 1
st1 = fileread('label_data_1.json');

%Read contents of File 2
st2 = fileread('label_data_2.json'); 

%Open a new JSON file in text mode
[fid,msg] = fopen('combined.json','wt'); 

%Write contents of File 1 and File 2 in the new file
fprintf(fid,'%s\n%s',st1,st2); 

%Close the open file
fclose(fid); 

Here "combined.json" will be the desired JSON file. 

Please refer the below documentation for fprintf : https://www.mathworks.com/help/matlab/ref/fprintf.html
