OlegK, Thanks for the response but it made me think of a couple of questions I had.

=> If you allow the cells to be editable in the grid, with this also change the JSON file on the server when the changes were saved?

=> What would happen if another user edited the grid while I was viewing it, would the changes immediately be shown on my view?

=> (Similar) If the server modified the JSON file (I have bash scripts that occasionally change my JSON files) would the user see the changes right away.
