我使用JodConverter和Open-Office创建了一个应用程序，用于将excel（.xlsx）转换为PDF，应用程序正常但我遇到了两个问题
输出PDF的页面是A4大小的形式，因为某些工作表内容已被切掉。因为我希望excel的每个工作表都像在一个页面中一样完整。
缺少工作表，如果我的Excel有8个工作表，我只能在PDF输出中获得两个或三个
即使我们尝试直接从开放办公室转换为pdf，它也会提出上述类似问题
Excel文件 - ss1.xlsx
输出PDF - work.pdf
任何人都可以告诉我一些解决方案吗
我的代码如下所示
public class MyConverter {
public static void main(String[] args) throws ConnectException {
File inputFile = new File("C:/Users/Work/Desktop/ss1.xlsx");
File outputFile = new File("C:/Users/Work/Desktop/work.pdf");
// connect to an OpenOffice.org instance running on port 8100
OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
connection.connect();
// convert
DocumentConverter converter = new OpenOfficeDocumentConverter(connection);
converter.convert(inputFile, outputFile);
// close the connection
connection.disconnect();
}

我使用（免费）PrimoPDF打印机驱动程序直接在Excel中创建PDF。 大量的页面（20+）是由于其中一个工作表中缺少“适合页面”打印选项的事实，如果我记得很清楚则是第3页。 更正后，打印所有工作表的命令仍然会生成2个PDF文件。 PrimoPDF要求两次输入文件名，而它只要求一个。 我假设您的程序只生成与第一部分对应的PDF，因为通常只生成一个PDF。我对2部分打印没有解释。这可能是由于其中一个工作表中的某些打印设置迫使打印以“两批”执行。例如，不同的分辨率值可能会阻止一批打印。 结论：解决方法是使用PrimoPDF进行打印，并使用Web上免费提供的程序连接2个PDF文件。对于持久的解决方案，您必须详细验证所有工作表的打印设置，并确保它们相同。

我担心我以前的答案不够明确。所以这就是本质：
显然，Excel只能生成所有工作表的页面分辨率相同的PDF。如果遇到具有不同（空白）分辨率的工作表，它只会停止生成输出而不发出任何警告。恕我直言这是Excel中的一个错误。幸运的是，解决方法很简单。
希望这能澄清我以前的答案。

您可以使用Microsoft Excel对PDF进行任何.xlsx转换，我目前正在开发一个使用Jacob的应用程序（Java Com Bridge），它是一个用于连接Microsoft Office程序的对象模型的瘦包装器，但它没有'支持开放式办公，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。 Link to Jacob
在调查我在Excel中发现的问题时 - ＆gt;页面设置，如果您将Fit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，因为它可能导致布局问题。
我做了一个小的实现，在Excel 2010和Jacob 1.18上进行了测试

以下是根据上述代码生成的PDF文件。注意第3页，内容有点斩断，当你删除wrap文本属性和合并单元格时，它生成正常。 Converted XLSX

这是为所有工作表设置相同页面参数的Excel VBA代码。抱歉，我不熟悉Openoffice编程，假设API类似：

Dim ws As Worksheet
For Each ws In ActiveWorkbook.Worksheets
ws.Activate
Setup_Page
Next
End Sub
