leveldb-tools provides a simple way to dump your LevelDB (esp. goleveldb ) database in a general, easily parsable cdbmake format.

It also provides a way to load from such formatted input.

leveldb-tools dump my.leveldb >my.cdbmake

leveldb-tools load my.leveldb <my.cdbmake

For example, cznic's kv database can be dumped in cdbmake format:

kvaudit -d my.kvdb | leveldb-tools load my.leveldb
