Here is the bounty file. To find the uuid of an entity, first locate it's data. It will be stored in the region file that the entity is in (unless it is a player of course). Navigate to the chunk the entity is in, and it will be one of the entries in the  section. Then find the entity's UUIDMost and UUIDLeast (these refer to the most and least significant digits of the UUID respectively). Copy the UUIDMost and paste it into a decimanl to hex converter that is capable of calculating the signed 2's complement (dec to hex converter I found). The hex signed 2's complement is the first set of 16 digits of the entity's UUID. Repeat this part of the UUIDLeast and that will give you the second set of 16 digits of the entity's UUID.
