Question

I’m able to get cells to format as Dates, but I’ve been unable to get cells to format as currency… Anyone have an example of how to create a style to get this to work? My code below show the styles I’m creating… the styleDateFormat works like a champ while styleCurrencyFormat has no affect on the cell.

private HSSFWorkbook wb; private HSSFCellStyle styleDateFormat = null; private HSSFCellStyle styleCurrencyFormat = null; 

……

public CouponicsReportBean(){     wb = new HSSFWorkbook();     InitializeFonts();  }  public void InitializeFonts() {     styleDateFormat = wb.createCellStyle();     styleDateFormat.setDataFormat(HSSFDataFormat.getBuiltinFormat('m/d/yy'));       styleCurrencyFormat = wb.createCellStyle();     styleCurrencyFormat.setDataFormat(HSSFDataFormat.getBuiltinFormat('$#,##0.00'));  } 

Answer 1

After digging through the documentation a bit more, I found the answer:

http://poi.apache.org/apidocs/org/apache/poi/hssf/usermodel/HSSFDataFormat.html

Just need to find an appropriate pre-set format and supply the code.

    styleCurrencyFormat.setDataFormat((short)8); //8 = '($#,##0.00_);[Red]($#,##0.00)'
