Description:

Open Babel is a free, open-source version of the Babel chemistry file
translation program. Open Babel is a project designed to pick up where
Babel left off, as a cross-platform program and library designed to
interconvert between many file formats used in molecular modeling,
computational chemistry, and many related areas.

Open Babel includes two components, a command-line utility and a C++
library. The command-line utility is intended to be used as a replacement
for the original babel program, to translate between various chemical file
formats. The C++ library includes all of the file-translation code as well
as a wide variety of utilities to foster development of other open source
scientific software.
