JodConverter does not support docx file in java

问题

I am using JodConverter to convert my .docx (Microsoft Office) files to pdf but somehow it does not covert and gives me the error.When If I tried to convert .doc documents to pdf then it works fine.I am using maven JodConverter plugin version 2.2.0 .

My question is that Is it possible to convert .docx files to pdf using JODCoverter ?

Disclaimer: I own the jodconverter.org domain and forked the original project on GitHub.

Little late to the party but you can use a fork of the original project, available on Maven:

JODConverter

It supports the docx and xlsx formats.

JodConverter version 2.2.1 couldn't guess DocumentFormat for docx. Though you could pass document format for input file as an argument.

final DocumentFormat docx = new DocumentFormat("Microsoft Word 2007 XML", DocumentFamily.TEXT, "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "docx");
converter.convert(inputFile, docx, outputFile, null);
