I use Pandoc to convert a tex file to docx. I used the following command
pandoc -s foo.tex --bibliography=foo.bib -o foo.docx But in the output word document, citation are in format of (author date), while I want just a number like [1].
The solution is to use a CSL file to format the citations. I used ieee.csl from https://github.com/citation-style-language/styles
pandoc -s foo.tex --bibliography=foo.bib --csl=ieee.csl -o foo.docx In the 2025 version of pandoc I needed to adjust the command in Ahmads answer. The following worked for me:
pandoc -s foo.tex --bibliography=foo.bib --citeproc --csl=ieee.csl -o foo.docx
Pandoccan use any CSL file to format your citations. Please check out the Zotero style repo and download a matching style.
