Hi Abhijit,

I don't immediately see any problem with your code, without actually running it...

If I were you, I'd try to add some logging into key places of the code, to figure out where exactly is the problem. Use LOG and DUMP macros, which produce a log when the application is compiled in debug mode. To see the log, just press Alt+L or go to Debug > View the logfile. I'd start with adding DUMP(json) after the loop. Also, I guess you already tried inspecting the values of id, by adding PromptOK. Does it show the names of fields you are expecting?

Also, the code seems little over-complicated. Have a look at examples in reference/Jsonize. It displays exactly what you want, saving large structures into json file (just not as dynamically as you try to do it). Also reference/SelectFile might be of some help.

Best regards,
Honza
