writing json to excel using java poi

You are calling createRow() way to often (i.e. once per cell). Make sure you only call it once per row. After that, call getRow() instead. — Erich Kitzmueller

But i want to print data in column wise. Any suggestions please — user2894607

Within the loop, replace createRow() with getRow() - you have already created the rows for the headers (even though apparently headers and contents do not match).

String table = [{}{}{}];
JSONArray arrayJson = new JSONArray(table);

FileOutputStream fos = null ;
