您可以使用 Microsoft Excel 将任何 .xlsx 转换为 PDF，我目前正在开发一个使用 Jacob 的应用程序，（Java Com Bridge）一个用于连接到 Microsoft Office 程序的对象模型的薄包装器，afaik 它不支持打开-office，但它在将 .xlsx 文件转换为 PDF 文件方面做得很好。它需要一些设置。链接到雅各布
在查看我在 Excel -> 页面设置中发现的问题时，如果将适合更改为 1 页宽和 1 页高，它会挤压每个工作表以适合 PDF 中的每个页面。我遇到的另一个问题是 wrap text 属性，使用它时要小心，因为它会导致布局问题。
我对此做了一个小实现，在 Excel 2010 和 Jacob 1.18 上进行了测试

这是从上述代码生成的 PDF 文件。请注意第 3 页，内容有点被截断，当您删除换行文本属性并合并单元格时，它会生成正常。转换后的 XLSX
