This web form converts a LaTeX file to Wikipedia markup. It works only for files written simply and without custom macros. The conversion is not perfect and some hand editing will be required. There is no error reporting - if something goes wrong, you get raw errors and they will be cryptic, or the browser window just goes blank. If you use BibTeX, paste in the window both the .tex and the .bbl file. Or you can download the source code and convert from the command line (you will need Perl 5 installed).
