Running pandoc -f markdown -t odt -o basic.odt basic.md on basic.md, which is as follows...

hello world

results in an odt file that LibreOffice is unable to open. The Libre Office error is: "The file 'basic.odt' is corrupt and therefore cannot be opened." The file can be opened in MSWord, but on save it warns "basic.odt may contain features that are not compatible with this format."

odfvalidator.org reports an error for the odt file as follows:
basic.odt/content.xml[2,1334]: Error: attribute "office:version" has a bad value

I am aware this may be an LO issue but pandoc-discuss is out of action so I thought I'd ask here.
Thanks.

Pandoc Version: 3.1.11
Libre Office: 7.6.4.1
Mac OS 14.1.2

I can't reproduce this on my end with pandoc 3.1.11 and LibreOffice for macOS:

Version: 7.4.2.3 / LibreOffice Community
Build ID: 382eef1f22670f7f4118c8c2dd222ec7ad009daf
CPU threads: 8; OS: Mac OS X 12.7.2; UI render: default; VCL: osx
Locale: en-US (en_US.UTF-8); UI: en-US
Calc: threaded

I can try updating LibreOffice to see if it makes a difference.

Upgrading to LibreOffice 7.6.4.1 -- I can still open basic.odt with no problems.
macOS 12.7.2, but hard to believe that a difference in macOS version would result in this difference.

Here's what I get on odfvalidator.org:

This is different from what you're seeing, so I'm really puzzled. Can you upload your basic.odt so I can compare it with mine?

[jgm]

To fix the validation error above, we need to put office:styles as the root node of a separate file, styles.xml:

[jgm]

I've fixed the issue with styles, but this doesn't seem to be your original issue.
My content.xml has office:version="1.3" which seems to work fine.

Thanks for looking into this! Have attached my 'basic.odt'; odfvalidator.org gives me this...

basic.odt

(I should maybe have mentioned that this is the 'Apple Silicon' version of LO)

I'll also mention that while I can unzip the odt file on the command line (unzip basic.odt -d file-content), changing the file extension to .zip in the Finder and double clicking to unzip gets me an 'unsupported format' error.

Think I found the source of the problem; it was line 2 in the default.opendocument template I was using, it finished with office:version="1.2">. Changing this to "1.3" fixed it 🙄 ...
Thanks for your help, have a good 2024!
