  The EXFOR library is a useful resource for many people in the field of
nuclear physics. In particular, the experimental data in the EXFOR library
serves as a starting point for nuclear data evaluations. There is an ongoing
discussion about how to make evaluations more transparent and reproducible. One
important ingredient may be convenient programmatic access to the data in the
EXFOR library from high-level languages. To this end, the complete EXFOR
library can be converted to a MongoDB database. This database can be
conveniently searched and accessed from a wide variety of programming
languages, such as C++, Python, Java, Matlab, and R. This contribution provides
some details about the successful conversion of the EXFOR library to a MongoDB
database and shows simple usage examples to underline its merits. All codes
required for the conversion have been made available online and are
open-source. In addition, a Dockerfile has been created to facilitate the
installation process.
