Question

I’m trying to write multiline text to excel cells.

cell.setCellValue("line1 \n line2");

But when I open the document, I see only one line until I double-click it for editing, then it becomes two-lined. Why is it so? Thanks

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);
