How to convert MongoDB archive file to JSON format?

If I dump a database like so:

mongodump --archive=out.mdb

Is there some way to convert out.mdb to a flat JSON file? If so, how? (for example, if I just wanted to restore a single document)

Solution

  • mongoexport

    I believe the only way is from the database, using mongoexport:

    mongoexport --db yourdb -c yourCollection --out yourCollection.json

    warning from mongo

    Just take notice of the following (from their website):

    WARNING

    Avoid using mongoimport and mongoexport for full instance production backups. They do not reliably preserve all rich BSON data types, because JSON can only represent a subset of the types supported by BSON. Use mongodump and mongorestore as described in MongoDB Backup Methods for this kind of functionality.
