I need to convert LaTeX into MediaWiki syntax. The formulas should stay the same, but I need to transform, for example \\chapter{something} into = something =
Yes Pandoc would be the easiest to do that.
pandoc -f latex -t mediawiki --metadata link-citations --bibliography=bibl.bib --csl=cslstyle.csl test.tex -o test.wiki
--metadata link-citations creates hyperlinks with your in-text citations and the bibliography. You can delete this part if not needed.
bibl.bib is the file of the bibliography you used
cslstyle.csl is the style of citation you want. There are lots of choices that can be downloaded from editor.citationstyles.org
test.tex is the file you want to convert from
test.wiki is the output file you want
all the files should be in the same folder otherwise locations should be specified
