Summary

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) - HTML formats (HTML 4 and 5) - Ebook

formats (EPUB v2 and v3, FB2) - Documentation formats (GNU TexInfo, Haddock) -

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) - 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.
