After create and arrange all the task on Gantt, is that anyway to get the latest Gantt task JSON back ?
We can create a task JSON and let Gantt to load it, now can it do it reversely?
The current task tree state is available in tasks.list:
Whenever a task is changed on the client side this array is updated so it always has up-to-date data.
You can serialize the data using JSON.stringify().
