====== Other conversions to and from (La)TeX ======

This page lists converters to and from LaTeX, as of May 6, 2021.

This list is not complete. Some older converters, which are still available on the internet
but have rather limited capabilities, //e.g.// only support the older word ''.doc'' format, are not listed.
The list also contains no recommendations.

===== To LaTeX, from... =====

==== troff ====

''Tr2latex'' assists in the translation of a ''troff'' document into LaTeX 2.09 format.
It recognises most ''-ms'' and ''-man'' macros, plus most ''eqn'' and some ''tbl'' preprocessor commands.
Anything fancier needs to be done by hand. Two style files are provided.
There is also a man page (which converts very well to LaTeX...).
''Tr2latex'' is an enhanced version of the earlier ''troff-to-latex'' (which is no longer available).

==== WordPerfect ====

''wp2latex'' is actively maintained, and is available either for Windows or for Unix systems:
[[http://www.penguin.cz/%7Efojtik/wp2latex/wp2latex.htm]]

Open source, GPLv2. Latest version: 3.96 (2021-04-27).

==== RTF ====

''rtf2latex2e'', by Ujwal Sathyam and Scott Prahl:
[[https://sourceforge.net/projects/rtf2latex2e/]]

Open source, GPL. Latest version: 2.2.3 (2016-09-17).\\
It will only convert RTF as saved from Word 2010 and earlier.
RTF saved from the newer versions of Word contains tags which cause ''rtf2latex2e'' to segfault.
Development of it seems to have stalled.

==== LibreOffice/OpenOffice ====

''Writer2LaTeX'': [[http://writer2latex.sourceforge.net/]]

Requires: OpenOffice or LibreOffice, and Java.\\
Open source, LGPL. Latest versions: stable 1.6.1 (2018-10-19), snapshot 1.9.3 alpha (2018-10-19) 

==== Microsoft Word (doc/docx) ====

  * ''docx2tex'': [[https://github.com/transpect/docx2tex/]]\\
Open source BSD 2-Clause “Simplified” License. Latest version: 1.6 (2021-01-25).\\
Requires: Java 1.7 up to 1.14.

  * ''wordtolatex'': [[http://www.wordtolatex.com/]] (commercial).

  * ''word2latex'' [[https://www.word2latex.net/]] (commercial).

  * ''Word-to-Latex'' [[https://www.grindeq.com]] (commercial).

  * ''docx2latex'' [[https://www.docx2latex.com/]] (commercial).

  * ''word2tex'' [[https://www.chikrii.com/products/word2tex/]] (commercial).

==== PDF ====

''Acrobat Reader'' (version 5.0 and later) or ''PDF Exchange Editor'' will output rather
feeble files that ''Word'' can read.

==== Microsoft Excel ====

''Excel2Latex'' converts an ''Excel'' file into a LaTeX ''tabular'' environment;
it comes as a ''.xla'' file which defines some ''Excel'' macros to produce output in a new format.
[[https://github.com/krlmlr/Excel2LaTeX]]

LaTeX Project Public License, version 1.3 or later. Latest version: 3.5.0 (2017-07-15).

Also online conversion: [[http://excel2latex.com/]].

==== runoff ====

[[wp>TYPSET_and_RUNOFF|Runoff]] is probably obsolete.

Peter Vanroose's ''rnototex'' conversion program is written in VMS Pascal.
The sources are distributed with a VAX executable.

==== refer/tib ====

There are a few programs for converting bibliographic data between BibTeX
and [[wp>Refer_(software)|refer/tib]] formats. The collection includes a shell script converter
from BibTeX to ''refer'' format as well. The collection is not maintained.


===== From LaTeX to... =====

==== LibreOffice or Microsoft Word ====

The current preferred free-software method is a two-stage process:
  - convert LaTeX to ''OpenOffice'' format, using the ''tex4ht'' command ''oolatex'';
  - open the result in ''LibreOffice'' or ''OpenOffice'' and "save as" a MS-Word document.

<note tip>
Note that ''LibreOffice'' itself is //not// on CTAN; see [[https://www.libreoffice.org/]]
or [[http://www.openoffice.org/]], though most Linux systems offer it
as a ready-to-install bundle.
</note>

''tex4ht'' can also generate OpenOffice ODT format, which may
be used as an intermediate to producing Microsoft Word format files.

==== Microsoft Word (other routes) ====

  * ''tex2word'': [[https://hunyadi.info.hu/levente/en/tex2word]]. Open source, GPL. Latest version: 2016-03-22 (development stalled).

  * ''LaTeXML'': [[https://dlmf.nist.gov/LaTeXML/]]. Open source, Creative Commons 0: “No Rights Reserved” (GPL compatible). Latest version: 0.8.5 (2020-11-17).

  * ''tex2word'': [[https://www.chikrii.com/products/tex2word/]] (commercial).

  * ''LaTeX-to-Word'': [[https://www.grindeq.com/]] (commercial).
 
  * Convert LaTeX via PDF: Acrobat Reader (version 5.0 and later) or PDF Exchange Editor will output rather feeble files that Word can read.

==== RTF ====

''latex2rtf'': [[http://latex2rtf.sourceforge.net/]].

Open source, GPL. Latest version: 2.3.18 (2020-06-23).\\
Converts only a limited subset of LaTeX markup; development stalled.

==== FrameMaker ====

''FrameMaker'' provides "import filters" to aid translation from alien formats
(presumably including TeX) to ''FrameMaker'' 's own.
Also see [[http://webhome.cs.uvic.ca/~nigelh/fm2latex.html]] (latest update 2015)
and [[http://www.cs.stir.ac.uk/~kjt/software/framemaker/#la_mml]] (latest update 2019).


===== Converters supporting multiple formats =====

==== SGML ====

A group at Ohio State University (USA) is working on
a common document format based on SGML, with the ambition that any
format could be translated to or from this one.

FIXME If it's related to the paper [[https://dl.acm.org/doi/10.1145/62506.62520|Difficulties in parsing SGML]], that may be very old news.

==== Pandoc ====

[[https://pandoc.org/]]

Open source, GPL. Latest version: 2.13 (2021-03-21).\\
Pandoc can convert between numerous markup and word processing formats, including,
but not limited to, various flavors of Markdown, HTML, LaTeX and Word docx.
Pandoc can also produce PDF output.
Pandoc’s enhanced version of Markdown includes syntax for tables, definition lists,
metadata blocks, footnotes, citations, math (only the new Office Math, not equation
editor/MathType), and much more -- but no pictures.
