Not getting proper json format in office module of node.js

[dijitha]

When i read an excel file using office module of node.js i got the output as
{ cell:
[ { row: 0, col: 0, '$t': 'hello' },
{ row: 0, col: 1, '$t': 'test' } ] }
{ cell: [ { row: 1, col: 0, '$t': 1 }, { row: 1, col: 1, '$t': 2 } ] }
{ cell: [ { row: 2, col: 0, '$t': 2 }, { row: 2, col: 1, '$t': 3 } ] }

But i need the output as correct json format like
[ { hello: '1', test: '2' },
{ hello: '2', test: '3' } ].

Can anyone help in getting this
