How to remove charts from Excel using apache POI?

问题

I will need to remove all the charts using Apache POI.

I tried using the following code :-

public XSSFSheet removeCharts(XSSFSheet sheet) {
    XSSFDrawing drawing = sheet.getDrawingPatriarch();
    List<XSSFChart> charts = drawing.getCharts();
    charts.stream().forEach(v -> {
        v.getCTChartSpace().setNil();
    });
    return sheet;
}

But on saving and then opening the sheet it says corrupted XML.

回答1:

Please try the below code :

sheet.getDrawingPatriarch().getCTDrawing().setNil();
