Other conversions to and from (La)TeX
- troff
- troff-to-latex, written by Kamal Al-Yahya at Stanford
  University (California, USA), assists in the translation of a
  troff document into LaTeX format.  It recognises most
  -msand-manmacros, 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...).  The program is
  copyrighted but free.
  tr2latex is an enhanced version of this
  troff-to-latex.
 
 
- WordPerfect
-  wp2latex
  has recently been much improved, and is now
  available either for MSDOS or for Unix systems, thanks to its
  current maintainer Jaroslav Fojtik.
- PC-Write
- pcwritex.arc is a
  print driver for PC-Write that "prints" a PC-Write
  V2.71 document to a TeX-compatible disk file.  It was written by Peter
  Flynn at University College, Cork, Republic of Ireland.
- runoff
-  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 refer/tib formats.
  The collection includes a shell script converter from BibTeX to
  refer format as well. The collection
  is not maintained.
- RTF
-  Rtf2tex, by Robert Lupton, is for
  converting Microsoft's Rich Text Format to TeX.  There is also a
  convertor to LaTeX by Erwin Wechtl, called rtf2latex.
  The latest converter, by Ujwal Sathyam and Scott Prahl, is
  rtf2latex2e; this system seems rather good already, and
  is still being improved.
  Translation to RTF may be done (for a somewhat
  constrained set of LaTeX documents) by TeX2RTF, which
  can produce ordinary RTF, Windows Help RTF (as well as
  HTML, conversion to HTML).
  TeX2RTF is supported on various Unix platforms and under
  Windows 3.1
 
- Microsoft Word
-  A rudimentary (free) program for converting
  MS-Word to LaTeX is wd2latex, which runs on MSDOS.
  Word2TeX and TeX2Word are 
  shareware translators from 
  Chikrii Softlab; users' reports are
  very positive.
  If cost is a constraint, the best bet is probably to use an
  intermediate format such as RTF or HTML.
  Word outputs and reads both, so in principle this route
  may be useful.
   Another, unlikely, intermediate form is PDF: Acrobat Reader
  for Windows (version 5.0 and later) will output rather feeble
  RTF that Word can read.
 
- Excel
-  Excel2Latex converts an Excel file
  into a LaTeX tabularenvironment; it comes as a.xlsfile which defines some Excel macros to produce
  output in a new format.
Wilfried Hennings' FAQ,
which deals specifically with conversions between TeX-based formats
and word processor formats, offers much detail as well as tables that
allow quick comparison of features.
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.  FrameMaker provides
"import filters" to aid translation from alien formats
(presumably including TeX) to FrameMaker's own.
