Q: How to write JSON data into excel or csv format Android? I am trying to dump my JSON response into excel sheet with .csv file after getting response from server. I have tried with poi-3.7.jar and poi-ooxml-3.11.jar libraries. But I am getting an empty excel sheet. 
Please check my below code for more reference.
My JSON URL http://vehiclerescue.in/ideadarpan_beta/api/reportApp/get_tsm_data
Code how I created rows:

try {
    if (response.isSuccessful()) {
        mProgressDialog.dismiss();
        try {
            String result = response.body().string();
            Log.d("files1st_reports", "***   " + result);

            JSONArray docs = new JSONArray(result);
            File file=new File(  Environment.getExternalStorageDirectory().getAbsolutePath() + "/gowthamguru"+"/tmp2/fromJSONss.csv");
            String csv = CDL.toString(docs);
            FileUtils.writeStringToFile(file, csv);

            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(file),"application/vnd.ms-excel");
            context.startActivity(intent);
        } catch (JSONException e) {
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

I hope this will Work Perfectly..
