can you provide a reproducible use case? the current code assumes that each XSSFHyperlink is for one cell and one cell only (see it is has a cell ref)

PS org.apache.poi.xssf.usermodel.XSSFSheet#removeHyperlink is annotated as an internal API - removing hyperlinks (in theory) should be done using the Cell removeHyperlink method.

Yes, I've used the cell method, but as it didn't work I looked at the code and I've seen, as you say, that it doesn't work because it expects a single cell.

I will try to submit a minimal reproducible example.

File to reproduce the error

Code to reproduce de error:

            try (InputStream fileStream = new FileInputStream("c:\\temp\\multiplehyperlinks.xlsx")) {
                XSSFWorkbook workbook = new XSSFWorkbook(fileStream);  //I
                Streams.stream(workbook.getSheetAt(0).rowIterator())
                        .flatMap(row -> Streams.stream(row.cellIterator()))
                        .filter(cell -> cell.getHyperlink() != null)
                        .forEach(Cell::removeHyperlink);

                assert  workbook.getSheetAt(0).getHyperlinkList().size() == 0;
           }

Current code doesn't support this (from sheet1.xml)


<hyperlink ref="A3:A5" r:id="rId2" display="http://www.apache.org" xr:uid="{DAEE6718-A7F1-4532-A628-07B4379C0500}"/>

It expects that the ref is a single cell.

Implementing this could be tricky.
* need to fix the getHyperlink logic to be aware the hyperlink cell ref can be a range
* removeHyperlink logic needs to handle case where you are removing a shared hyperlink from just one cell. If you remove from the middle of the range of cells then you need to create extra hyperlinks to replace the one you remove - it might be easier initially to create single cell hyperlinks on the cells that are part of the original shared range but that we have not received a request to remove the shared hyperlink from
* XSSFRow removeCell does not seem to try to handle removing related hyperlinks
* the row shifter logic will need to take into account the fact the hyperlink might be shared by cells on separate rows - like with removeHyperlink if might be tidier to make the hyperlink on the destination a non-shared hyperlink

Joan - this will be fixed eventually but if you want to remove hyperlinks that have cell refs that span many cells - as a workaround - you could get the hyperlinks from the sheet and iterate over them to find the ones you want to remove and change the cell ref to be one that is just a simple single-cell cell ref and then you can remove that hyperlink using that sheet.removeHyperlink or the cell.removeHyperlink (the sheet.removeHyperlink may need to be changed in the next release to accommodate the fix for this issue.

PJ Fanning - Thank you very much for your support and the provided workaround.

I've added a partial fix - r1892189

I've already updated POI trunk so that XSSFCell#getHyperlink will find a shared hyperlink if there is one

I added support for removing a hyperlink from one cell and keeping the hyperlink on other cells (when the original hyperlink is a shared one).
