Pandoc is a Haskell library for converting from one markup format to another. The formats it can handle include

light markup formats (many variants of Markdown, reStructuredText, AsciiDoc, Org-mode, Muse, Textile, txt2tags, djot) HTML formats (HTML 4 and 5) Ebook formats (EPUB v2 and v3, FB2) Documentation formats (GNU TexInfo, Haddock, Vimdoc) Roff formats (man, ms) TeX formats (LaTeX, ConTeXt) Typst XML formats (DocBook 4 and 5, JATS, TEI Simple, OpenDocument) Outline formats (OPML) Bibliography formats (BibTeX, BibLaTeX, CSL JSON, CSL YAML, RIS) Word processor formats (Docx, RTF, ODT) Interactive notebook formats (Jupyter notebook ipynb) Page layout formats (InDesign ICML) Wiki markup formats (MediaWiki, DokuWiki, TikiWiki, TWiki, Vimwiki, XWiki, ZimWiki, Jira wiki, Creole) Slide show formats (LaTeX Beamer, PowerPoint, Slidy, reveal.js, Slideous, S5, DZSlides) Data formats (CSV and TSV tables, Excel spreadsheets) PDF (via external programs such as pdflatex or wkhtmltopdf)

Pandoc can convert mathematical content in documents between TeX, MathML, Word equations, roff eqn, typst, and plain text. It includes a powerful system for automatic citations and bibliographies, and it can be customized extensively using templates, filters, and custom readers and writers written in Lua.

For the pandoc command-line program, see the pandoc-cli package.
