Pandoc is a free-software document converter, widely used as a writing tool (especially by scholars) and as a basis for publishing workflows. It was created by John MacFarlane, a philosophy professor at the University of California, Berkeley.
You can
install Pandoc on Ubuntu Linux by
downloading the .deb file and execute:
sudo dpkg -i pandoc-3.6.3-1-amd64.deb
You can then convert between documents. For example, convert LaTeX doc into .docx:
