Multiline text in Excel cells

I found that you have to now include a third step after you follow the accepted answer to this question. You have to auto-size the column after you've added all of your data.

Assuming you're concerned about column 2,

sheet.autoSizeColumn(2);

See this example from Apache for context. It works for me with Java 8, poi-3.15.jar, and Excel for Mac.

You need to set the row height to accomodate two lines of text.

row.setHeightInPoints((2*sheet.getDefaultRowHeightInPoints()));

You need to set the wrap text = true to get the new line. Try this : Here wb is the Workbook.

 CellStyle cs = wb.createCellStyle();
 cs.setWrapText(true);
 cell.setCellStyle(cs);
