Pandoc

Pandoc is a free-software document converter, widely used as a writing tool (especially by scholars)[2] and as a basis for publishing workflows.

[3] It was created by John MacFarlane, a philosophy professor at the University of California, Berkeley.

[5] Plug-ins for custom formats can also be written in Lua, which has been used to create an exporting tool for the Journal Article Tag Suite, for example.

[7] This allows the program to serve as a simpler alternative to LaTeX for producing academic writing in Markdown with inline citation keys.

[8] Or the program can be used to convert any bibliographic data stream in the accepted formats into a list of citations in a chosen style.
