### 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 `-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...). 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. Word2 TeX and TeX 2Word 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 `tabular` environment; it comes as a `.xls` file 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.
