Description dollinger.florian 2017-03-17 10:35:13 UTC
I am trying to copy the whole Style of some Cells from one Worksheet to another.
At the moment I am using .cloneStyleFrom(), but this way a new Style is created everytime - since there is no way to detect if the new Style already exists and can be reused.

XSSFCellStyle newStyle = dstSheet.getWorkbook().createCellStyle();
// this creates a new style for every single cell, bad!

should become something like:

XSSFCellStyle newStyle = null;
XSSFCellStyle exisiting = dstSheet.getWorkbook().searchForCellStyle(oldCell.getCellStyle());
// returns the already existing style (if), or null

if(existing == null){

  newStyle = dstSheet.getWorkbook().createCellStyle();

} else {



I'll give it a try to patch it, if somebody has a good idea - please let me know!


Another Way would be to use CellUtil.setCellStyleProperties(), but it's not working for not-indexed colors, fonts, ...

Also a CellUtil.getCellStyleProperties() function would be nice.

(But thats another issue, i will do that afterwards)

By the way, the following would in fact work - but makes only sense within the same Workbook!

for(int p = 0; p < dstSheet.getWorkbook().getNumCellStyles(); p++){


applyAlignment="1" borderId="0" fillId="0" fontId="0" numFmtId="0" xfId="0"
on workbook 1

applyAlignment="1" borderId="0" fillId="0" fontId="0" numFmtId="0" xfId="0"
on workbook 2

may be referencing different fills, fonts, ... (the same index does not mean it is really the same on both workbooks)
