How do I dump an entire MongoDB database as text/json?

Question

How can I dump an entire MongoDB database as text (plain text, json, or CSV)?

I'm using an application I'm not too familiar with. I'd like to

• clear the database
• load seed data
• dump the whole db as text
• do some stuff
• dump again

then diff the two!

Answer 1

Using mongodump and bsondump:

Step 1 Dump the entire database to BSON files:

 mongodump --db db1

Step 2 Convert each BSON file to JSON file:

for f in dump/db1/*.bson; do bsondump "$f" > "$f.json"; done

Hope it's helps!
