angularjs - Why am I am not able to view data added to my excel using ng-csv? -

this html looks like:

        <button type="button" class="btn btn-info btn-xs btn-block navigation-button" ng-csv="main.csvdata"  lazy-load="true" filename="test.csv">export csv</button> 

and main.csvdata contains:

[id: "1383817510", path: "https://amazonaws.com", a: 0, bi: 0, bri: 0] 

i know doing wrong. setting array in array instead of object.
