As a side-note to Dan Ritter's 'yes', MongoDB natively stores records in
JSON, with a binary-encoding extension ('BSON') available.

Note: as of October 2018, MongoDB is no longer open source.  Thus,
RHEL/CentOS/Fedora, Debian, and increasingly other distributions have
dropped it.  (More should follow as distros do package refresh.)

Last AGPL versions of MongoDB were 4.0.3 (stable) and 4.1.4 (beta).  
A fork, TokMX, remains under AGPL, with some files under Apache License
2.0 and one library under GPLv2 with patent licence.

There are a other interesting 'nosql'[1] databases that continue to be
open source, but it's worth mentioning that the MongoDB licence change
was inspired by a similar licensing move by Redis Labs that immediately
inspired a fork of Redis called KeyDB.

[1] When first coined, this rather vague term meant 'relational but not
SQL-based', but has been increasingly borrowed to apply to databases
not satisfying relational-database principles such as  atomicity,
consistency, isolation and durability guarantees.  Caveat emptor.
