i have data in db which reads 

> 
> data=a,b,c,d
> 
>

i need to export this data to excel file under a single cell using java which should read like this

> 
> a
> 
> 
> b
> 
> 
> c
> 
> 
> d
> 
>

i have done the exporting part but unable to bring the values like the above under a single cell. i have presently done this but its wrong.

```
   String Data=getDataVO.getData();

     String Data1[]=Data.split(",");

for(int i=0;i<=Data1.length;i++){

   String dt=Data1[i].concat(newline);
           ExcelUtil.setCell(row, ExcelConstants.ONE, dt, style);}

```
