Grid implementation in Keyword driven framwork

Hi Ashish/team,

I have keyword driven framework in my organization and i would like to make changes into that for multiple browser support across nodes.

We have one TestNG test which reads all excel data and run set of test cases based on execution flag value set in excel. this typically happens in such framework.

But by just setting @Test (parallel=true) i can't split up test cases for grid execution. Also i will do so how i will write back result to one excel. (I doubt i might see thread issue)

Could you please suggest something for this ?
