Export Data from MongoDB
To export data from a MongoDB database using MongoDB Tools, particularly mongodump and mongoexport, follow the appropriate method based on your use case:
✅ Option 1: Use mongoexport
Exports collection data in JSON or CSV format.
🔹 Example: Export a collection to JSON
mongoexport --uri="mongodb://localhost:27017" \
--db=mydatabase \
--collection=mycollection \
--out=mycollection.json
🔹 Example: Export to CSV (with selected fields)
mongoexport --uri="mongodb://localhost:27017" \
--db=mydatabase \
--collection=mycollection \
--type=csv \
--fields=name,age,email \
--out=mycollection.csv
✅ Option 2: Use mongodump
Creates a binary backup of the database or collection (good for restoring later using mongorestore).
🔹 Example: Dump entire database
mongodump --uri="mongodb://localhost:27017" \
--db=mydatabase \
--out=./dump/
🔹 Example: Dump a single collection
mongodump --uri="mongodb://localhost:27017" \
--db=mydatabase \
--collection=mycollection \
--out=./dump/
🔄 To Restore Data Later:
🔹 Using mongorestore for a full dump
mongorestore --uri="mongodb://localhost:27017" ./dump/
