How can I rotate the text within an HSSFCell class of Apache POI?
Use HSSFCellStyle, that class has a method called setRotation(short rotation) which will rotate the text. All you do is apply the cell style to a cell:
HSSFCellStyle myStyle = workbook.createCellStyle();
myStyle.setRotation((short)90);
HSSFCell c = row.createCell(columnNumber);
c.setCellStyle(myStyle);
CellStyle cssVertical = wb.createCellStyle();
cssVertical.setFont(f);
cssVertical.setRotation((short)90);
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet();
XSSFRow row = sheet.createRow(1);
XSSFCell cell = row.createCell(1);
XSSFCellStyle cs = workbook.createCellStyle();
cs.setRotation((short) 90); // set text rotation
cs.getStyleXf().setApplyAlignment(true); // <<< Important
cell.setCellValue("Vertical Text");
cell.setCellStyle(cs);
workbook.write(new FileOutputStream("out.xlsx"));
Apache POI 3.17, need to manually add alignment="true" attribute in cellXfs section.

I create an Excel file through Apache POI XSSF and I lock the sheet with a password so user can't change the value of the first two row and first five columns (I lock the sheet and allowed editing of other cells). All work fine, the only problem is that the user can't resize the column so he can neither change nor resize the columns to read all the cells value.
Is it possible to allow column resize even if the sheet is protected?
Thi is my configuration
workbook = new XSSFWorkbook();
sheet = workbook.createSheet("Sheet1");
sheet.protectSheet("passwordExcel");
unlockedNumericStyle = workbook.createCellStyle();
unlockedNumericStyle.setLocked(false);
// Format cell for date
dateStyle = workbook.createCellStyle();
CreationHelper createHelper = workbook.getCreationHelper();
dateStyle.setDataFormat(createHelper.createDataFormat().getFormat("dd/mm/yyyy"));
sheet.autoSizeColumn(1);
I read about lockFormatCell() but I don't understand if it can help me. Thanks
To be able resizing the column size while sheet is protected, you will need setting XSSFSheet.lockFormatColumns to false.
Complete example:
import java.io.FileOutputStream;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.*;
public class CreateExcelXSSFProtectedSheet {
public static void main(String[] args) throws Exception {
Workbook workbook = new XSSFWorkbook();
CreationHelper createHelper = workbook.getCreationHelper();
CellStyle unlockedNumericStyle = workbook.createCellStyle();
unlockedNumericStyle.setDataFormat(createHelper.createDataFormat().getFormat("$#,##0.00_);[Red]($#,##0.00)"));
unlockedNumericStyle.setLocked(false);
CellStyle dateStyle = workbook.createCellStyle();
dateStyle.setDataFormat(createHelper.createDataFormat().getFormat("dd/mm/yyyy"));
Sheet sheet = workbook.createSheet();
Row row = sheet.createRow(0);
Cell cell = row.createCell(1);
cell.setCellValue("some data");
row = sheet.createRow(1);
cell = row.createCell(1);
cell.setCellValue(-123456789.0123456);
cell.setCellStyle(unlockedNumericStyle);
row = sheet.createRow(2);
cell = row.createCell(1);
cell.setCellValue(new java.util.Date());
cell.setCellStyle(dateStyle);
((XSSFSheet)sheet).lockFormatColumns(false);
sheet.protectSheet("passwordExcel");
sheet.autoSizeColumn(1);
FileOutputStream out = new FileOutputStream("CreateExcelXSSFProtectedSheet.xlsx");
workbook.write(out);
out.close();
workbook.close();
}
}
I am using poi-3.6 and I need to update my source files to poi 3.17. I need to know 'XSSFCellStyle.SOLID_FOREGROUND', 'XSSFCellStyle.ALIGN_RIGHT' and 'HSSFCellStyle.BORDER_MEDIUM' alternatives in poi 3.17.
CellStyle fontBoldedCell = ExcelCommon.getFontBoldedCell(workbook);
Sheet sheet = workbook.getSheetAt(0);
row = sheet.createRow(currrow++);
cell = row.createCell(0);
cell.setCellValue("Total Records");
cell = row.createCell(1);
cell.setCellValue(count);
cell.setCellStyle(ExcelCommon.getAligneCell(workbook, null, XSSFCellStyle.ALIGN_RIGHT));
Font font = workbook.createFont();
font.setBold(true);
CellStyle style = workbook.createCellStyle();
style.setFont(font);
style.setFillForegroundColor(IndexedColors.GREY_25_PERCENT.getIndex());
style.setFillPattern(XSSFCellStyle.SOLID_FOREGROUND);
style.setBorderTop(BorderStyle.THIN);
style.setBorderRight(BorderStyle.THIN);
style.setBorderLeft(BorderStyle.THIN);
style.setBorderBottom(BorderStyle.THIN);
return style;
CellStyle style = workbook.createCellStyle();
Font font = workbook.createFont();
style.setFont(font);
style.setBorderBottom(HSSFCellStyle.BORDER_MEDIUM);

I'm trying to set an RGB Color Value using XSSFColor setFillForeground() method below
XSSFWorkbook workbook= new XSSFWorkbook();
CellStyle style = workbook.createCellStyle();
Style.cloneStyleFrom(headerStyle);
Style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
XSSFColor color = new XSSFColor(new java.awt.Color(215,228,188)); //accepts a short value
style.setFillForegroundColor(color .getIndexed());
Sheet sheet = workbook.createSheet(sheetName);
Row headerRow = sheet.createRow(0);
Cell cell = headerRow.createCell(i);
cell.setCellStyle(style);
I'm passing the short value however my foreground is getting set to black no matter what the RGB value. I haven't yet discovered why this is - any ideas?
The getIndexed() method in XSSFColor has Javadocs that state that it's for backwards compatibility. Basically, XSSF has no pallette, so it's useless to set an index of color in a CellStyle.
However, XSSF has its own method of setting the foreground color in a style -- using the colors directly. Use the overload of setFillBackgroundColor that directly takes a XSSFColor. It only exists in XSSFCellStyle, not the interface CellStyle, so cast it as a XSSFCellStyle first.
((XSSFCellStyle) style).setFillForegroundColor(color);
You can check the example provided by the Apache Colors and Fills
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet();
XSSFRow row = sheet.createRow(0);
XSSFCell cell = row.createCell( 0);
cell.setCellValue("custom XSSF colors");
XSSFCellStyle style1 = wb.createCellStyle();
style1.setFillForegroundColor(new XSSFColor(new java.awt.Color(128, 0, 128), new DefaultIndexedColorMap()));
style1.setFillPattern(FillPatternType.SOLID_FOREGROUND);
How can I write my full value in cell with help of poi ?
i.e. if value is 1000.000 then how can I write this full value without truncating 000 after "." with POI? means I want full value.
In my case, it only takes 1000 but this is not right format for me.
You have to set "Format" of the cell where this number is getting stored. Example code:
Workbook wb = new HSSFWorkbook();
Sheet sheet = wb.createSheet("format sheet");
CellStyle style;
DataFormat format = wb.createDataFormat();
Row row;
Cell cell;
short rowNum = 0;
short colNum = 0;
row = sheet.createRow(rowNum++);
cell = row.createCell(colNum);
cell.setCellValue(11111.25);
style = wb.createCellStyle();
style.setDataFormat(format.getFormat("0.0"));
cell.setCellStyle(style);
row = sheet.createRow(rowNum++);
cell = row.createCell(colNum);
cell.setCellValue(11111.25);
style = wb.createCellStyle();
style.setDataFormat(format.getFormat("#,##0.0000"));
cell.setCellStyle(style);
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
