I want to export the whole data from one of my collections in mongodb to a csv file.
This is how my db looks like:
"Tags",
"checkouts",
"imports",
"products"
I am trying to export "checkouts".
I am connected to the db through the terminal and I tried the following commands:
mongoexport --db nameofdatabase --collection checkouts --out coll.json
mongoexport --db nameofdatabase --collection checkouts --type=csv --fields --out /opt/backups/contacts.csv
The error message I get after running both commands command is : "Unexpected identifier"
MongoExport cannot be used in the mongo shell. It is a terminal command like mongo.

During my studying of MongoDB I tried to dump a collection from training course's mongo database.
I tried both mongodump and mongoexport.
My shell command is like
mongoexport --uri="mongodb://<my-username>:<my_password>#<replica-1>.mongodb.net:27017,<replica-2>.mongodb.net:27017,<replica-3>.mongodb.net:27017/<database>?replicaSet=<replica-set>" --collection=<collection-name> --out=<collection-name>.json --ssl
When I run the command, nothing happened: no response, no new local files, no errors, only cursor flashes.
How can I export collections by the uri?
--forceTableScan
option can be used along with mongodump & --uri option
mongodump --uri
mongodb+srv://<user_name>:#.mongodb.net/db_name
--forceTableScan --collection <collection_name> --out ./dump/
I'm working with mongodb 2.4.3 and I cannot get mongoexport to work. The error message I get with each command is:
"JavaScript execution failed: SyntaxError: Unexpected identifier"
At first I thought the problem was with my query parameters, which were long. But find() worked fine with the query so I know that the syntax is ok. I then created a new collection using the query and tried exporting the collection with the following:
mongoexport --db Oct2012 --collection sept8subset --csv --fields "text","created_at","user.screen_name","user.followers_count" --out sept8.csv
mongoexport --db Oct2012 --collection sept8subset --csv --fields text,created_at,user.screen_name,user.followers_count --out sept8.csv
mongoexport -d Oct2012 -c sept8subset --csv --fields text,created_at,user.screen_name -o sept8.csv
mongoexport --db Oct2012 --collection sept8subset --dbpath ~/db (should need dbpath as mongod instance is running)
mongoexport --db OCt2012 -collection sept8subset -o sept8.txt
mongoexport --db Oct2012 --collection sept8subset
In each case, I get "JavaScript execution failed: SyntaxError: Unexpected identifier". Where could that SyntaxError be??
The collection I'm trying to copy has 50,339 objects. In case it is just too big for mongoexport to handle, I took 5 documents out of the collection to make a new collection. I then tried to export them using same command structure as above. I still get the same error message.
Now I'm wondering if the problem is that mongoexport can't work with data involving dates. MongoDB documentation states that I may want to write my own export script using a client driver.
Does anyone have an idea of what my problem is here? Many thanks if you can help out.
I found out that running mongoexport from the mongo client--as I was doing--is incorrect. Mongoexport is executed at the command prompt.
I ran into this too and I solved it executing the command from the path/bin where 'mongoexport' is located.In my case :
my_path: /usr/local/Cellar/mongodb/2.4.4-x86_64/bin
"mongoexport -d book -c shelf"
'mongod' is located one step upper from 'mongoimport' , 'mongoexport', etc...
I am writing this query in mongo shell
mongoexport --db database_name --collection collection_name --out filename.json
query to export but the error is
SyntaxError: unexpected identifier
can anybody help me ?
Mongoexport is a terminal command line utility to export data, not mongoshell functional directive.
Try running the same in terminal.
$ mongoexport --db database_name --collection collection_name --out filename.json
Make sure you have all the utilities that come with mongo added to your path.
show dbs

mongoexport --db TestDB --collection MyCollection --type=csv --fields MyNames --out D:\contacts.csv

From that error message it looks like you are still in the mongo shell. mongoexport is a separate utility. You need to exit the mongo shell, the command is just exit. Then enter your mongoexport command again on the command line.
