Thank you for your question! This error indicates that the .docx file was not valid. Specifically, the fldCharType attribute is required on fldChar elements, by the open office specification, and the error indicates that this required attribute is missing.

Since you saved this file with python-docx (from the original .doc file), you might want to raise an issue with python-docx.

I had the same error using the library with *.docx that were saved from a template *.dotx file. Is there any easy work around you can think of? Documents have a lot of checkboxes, tables and dropdown fields. This library was looking like the solution with my tests then this element is missing on the documents. Thanks.

If you can share a *minimal* document which produces this error, I'd be happy to take a look (in a gist, perhaps, or I just noticed files can be dropped onto the response field on GitHub, so that might work for sharing problem documents. Very minimal problem documents are better -- e.g. a document with a single check box or dropdown, though feel free to provide a few unique example documents (e.g. one with a checkbox, another with a dropdown). I've been meaning to document how the document walker can be modified to implement new rules, and this might present a solution to handling this issue. Heads up though, I maintain this pretty much on my own time, so it might be a few days before I can dive into it...

Thanks for the response. [https://github.com/turbomanson/docx-scrape/blob/master/simplify_minimal_example.ipynb] Here is a complete example with an example docx generating error. I canʻt reproduce the error with a minimal document. I would appreciate if you could take a look, but I understand this is on your own time.

I had the same error with some tables in the docx. Is there any docx format for simplify_docx? In other words, what attribute in docx files that simplify_docx can't deal with?
Thanks.

请问，这个问题解决了吗？

according to the README

This project relies on the python-docx package which can be installed via
pip install python-docx. However, as of this writing, if you wish to
scrape documents which contain (A) form fields such as drop down lists,
checkboxes and text inputs or (B) nested documents (subdocs, altChunks,
etc.), you'll need to clone this fork of the python-docx package

You need a modified version of python-docx to support parsing forms, otherwise python-docx will not parse fldChar and cause this issue.

I ran into this error recently upon parsing a docx file, and using the forked python-docx didn't solve it for me. Instead I got this error:

    143 
    144         if options.get("remove-leading-white-space", True):
