I have a json like  
{  
"230":{"startDatetime":"2017-07-21T07:00:00","endDatetime":"2017-08-07T06:59:59"},  
"232":{"startDatetime":"2017-07-21T07:00:00","endDatetime":"2017-08-07T06:59:59"}  
}  
and i need to convert to  
[  
{"location":"230","startDatetime":"2017-07-21T07:00:00","endDatetime":"2017-08-07T06:59:59"},{"location":"232","startDatetime":"2017-07-21T07:00:00","endDatetime":"2017-08-07T06:59:59"}  
]

Can we do this in logstash?

Yes, but as I suspect the 230 and 232 are dynamic and not something you can hardcode into your configuration you need to use a ruby filter.
