Question

我想将输入的Excel文件转换为输出XML文件。

如果有人在java中有任何解决方案如何获取输入Excel文件以及如何写入XML作为输出，请提供任何代码或任何URL或任何其他解决方案。

谢谢，

Answer 1

查看jexcel或Apache POI库以便在Excel文件中读取。

创建XML文件很简单，只需将XML直接写入文件，或者附加到XML文档，然后使用标准Java库或Xerces或类似文件将其写出来。

Answer 2

我最近在Java中将Excel（xlsx）转换为xml。我假设excel中的每一行都是一个单独的对象。以下是我遵循的步骤： -

使用Apache POI阅读Excel文件
创建了一个xsd文件生成相应的类
使用类中生成的getter / setter方法读取创建的每一行，创建相应的对象和初始值
将对象添加到只包含相同类型对象的arraylist
使用Jaxb将arraylist对象标记为输出文件

JExcel对我来说很容易使用。将jxl.jar放在类路径上并编写如下代码：

    File excelFile = new File(excelFilename);

    // Create model for excel file
    if (excelFile.exists()) {
        try {
            Workbook workbook = Workbook.getWorkbook(excelFile);
            Sheet sheet = workbook.getSheets()[0];

            TableModel model = new DefaultTableModel(sheet.getRows(), sheet.getColumns());
            for (int row = 0; row < sheet.getRows(); row++) {
                for (int column = 0; column < sheet.getColumns(); column++) {
                    String content = sheet.getCell(column, row).getContents();
                    model.setValueAt(content, row, column);
                }
            }

            previewTable.setModel(model);
        } catch (Exception e) {
            JOptionPane.showMessageDialog(null, "Error: " + e);
        }

    } else {
        JOptionPane.showMessageDialog(null, "File does not exist");
    }

File excelFile = new File(excelFilename);

// Create model for excel file
if (excelFile.exists()) {
    try {
        Workbook workbook = Workbook.getWorkbook(excelFile);
        Sheet sheet = workbook.getSheets()[0];

        TableModel model = new DefaultTableModel(sheet.getRows(), sheet.getColumns());
        for (int row = 0; row < sheet.getRows(); row++) {
            for (int column = 0; column < sheet.getColumns(); column++) {
                String content = sheet.getCell(column, row).getContents();
                model.setValueAt(content, row, column);
            }
        }

        previewTable.setModel(model);
    } catch (Exception e) {
        JOptionPane.showMessageDialog(null, "Error: " + e);

} else {
