mongoexport -h db.mysite.com -u myUser -p myPass -c myCollection
But the response I get is:
ERROR: too many positional options
What's that about?
I had this same problem. In my case, I was using mongoexport with the --query option, which expects a JSON document, such as:
mongoexport ... --query {field: 'value'} ...
I needed to surround the document with quotes:
mongoexport ... --query "{field: 'value'}" ...
I had the same problem. Found a group post somewhere which said to remove the space between the '-p' and the password, which worked for me.
Your sample command should be:
mongoexport -h db.mysite.com -u myUser -pmyPass -c myCollection
The same error I have encountered while importing a csv file.
But its just, the fact that the field list which you pass for that csv file import may have blank spaces.
Just clear the blank spaces in field list.
Its the parsing error.
I had the same issue with mongodump. After searching a bit, I found out that using the --out parameter to specify the output directory would solve this issue. The syntax for using the out parameter is
mongoexport --collection collection --out collection.json
Also in case your Mongodb instance isn't running, then you could use the --dbpath to specify the exact path to the files of your instance.

I had the same issue with the mongoexport utility (using 2.0.2). My fix was to use the FULL parameter name (i.e. not -d, instead use --db).
Sometimes editor will screw it up (such as evernote). I fixed the issue by retyping the command in terminal.
I was also stuck in same situation and found what was causing it.
Make sure you are exporting in CSV format by adding parameter --type csv
Make sure there are no spaces in fields name,
Example: --fields _id, desc is wrong but --fields id,desc,price is good
This also works if you place the -c option first. For me, this order does work:
mongoexport -c collection -h ds111111.mlab.com:11111 -u user -p pass -d mydb
You can also leave the pass out and the server will ask you to enter the pass. This only works if the server supports SASL authentication (mlab does not for example).
for the (Error: Too many arguments)

Had a similar issue

$try 'mongorestore --help' for more information
Simply fix for me was to wrap the path location in quotes " "

I had the same issue with starting mongod. I used the following command:
./mongod --port 27001 --replSet abc -- dbpath /Users/seanfoley/Downloads/mongodb-osx-x86_64-3.4.3/bin/1 --logpath /Users/seanfoley/Downloads/mongodb-osx-x86_64-3.4.3/log.1 --logappend --oplogSize 5 --smallfiles --fork
The following error message appeared:
Error parsing command line: too many positional options have been specified on the command line
What fixed this issue was removing the single space between the '--' and 'dbpath'
I had the same issue while using the "mongod --dbpath" command. What I was doing looked somewhat like this:
mongod --dbpath c:/Users/HP/Desktop/Mongo_Data
where as the command syntax was supposed to be:
mongod --dbpath=c:/Users/HP/Desktop/Mongo_Data
This worked for me. Apart from this one may take a note of the command function and syntaxes using the mongod --help command.
In my case, I had to write the port separately from the server connection. This worked for me:
mongoexport --host=HOST --port=PORT --db=DB --collection=COLLECTION
--out=OUTPUT.json -u USER -p PASS
Create a json file in the same folder where you have your mongod.exe.
eg: coll.json
and open a command prompt in this folder.
type this below in CMD.
mongoexport --db databasename --collection collectionname --out
coll.json
and you will see like a progress bar very cool exporting all data.

trying mongodump with following options and get "positional arguments not allowed"
mongodump --host=hostname --port=27017 --db=db --out=/path --oplog --gzip
tried mongodump -h hostname -d dbname and that works
What does the message
positional arguments not allowed
mean?
You got the syntax wrong in the first one. You need to remove the = sign. See documentation.
mongodump --host hostname --port 27017 --db db --out /path --oplog --gzip
mongodump -d<dbname> -o <backUpPath>
like this:
mongodump -d projectdb -o /Users/zhangzhanqi/Desktop/backup_mongo/aaa
The syntax has been changed to replacement of = with space character in front of the argument names. To clear the point with a descriptive answer, I put two general forms with long argument and short argument names.
Long parameter form:
mongodump --host hostname --port 27017 --db db --out /path --oplog --gzip
Short parameter form:
mongodump -h hostname -p 27017 -d db -o /path --oplog --gzip
You can find more explanation and examples in the following link:

I am getting an error after executing this command:
mongoexport --db records --collection source_list --csv --out C:\bcopy.csv
record is my DB n source_list is my collection
It displays this message:
assertion: 9998 you need to specify fields
I also tried to specify fields but it is giving me the same error.
What changes should i make in the command to get a backup of my collection or is there any other way to do so ?
Here's sample command that specifies fields to export:
mongoexport -h 127.0.0.1 --port 27018 --db mydb --collection system.profile --csv --out profile.csv --fields ns,millis,numYield,nscanned
In my case --headerline helped. I had around 60 columns, enumerating them with -f would be quite cumbersome.
--headerline
If using “--type csv” or “--type tsv,” use the first line as field names. Otherwise, > mongoimport will import the first line as a distinct document.
Seems like you should be using -f paramater to choose the fields that will be exported to csv file. There is a bug reported for this case to change the explanation as the error message is not informative enough.

How do I export the results of a MongoDB command to a flat file
For example, If I am to get db.collectionname.find() into a flat file.
I tried db.collectionname.find() >> "test.txt" doesnt seem to work.
you can try the following from the command line
mongo 127.0.0.1/db --eval "var c = db.collection.find(); while(c.hasNext()) {printjson(c.next())}" >> test.txt
assuming you have a database called 'db' running on localhost and a collection called 'collection' this will export all records into a file called test.txt
If you have a longer script that you want to execute you can also create a script.js file
and just use
mongo 127.0.0.1/db script.js >> test.txt
I hope this helps
I know of no way to do that from the mongo shell directly, but you can get mongoexport to execute queries and send the results to a file with the -q and -o options:
mongoexport -h mongo.dev.priv -d models -c profiles -q '{ $query : { _id : "MRD461000" } }' -o MRD_Series1.json
The above hits queries the profiles collection in the models database grabbing the JSON document for _id = "MRD641000". Works for me.
Use this
mongo db_name --username user --password password < query1.js >> result.txt
Try this - returns a json file with the data of the query, you can change .json for .txt and other.
mongoexport --db products --collection clicks --query '{"createdInt":{$gte:20190101}, "clientId":"123", "country":"ES"}' --out clicks-2019.json
Having missed the db needing to be the actual db in Peshkira's answer, here is a general syntax for a one liner in shell (assuming no password):
mongo <host>:<db name> --eval "var x = <db name>.<collection name>.<query>; while(x.hasNext()) { printjson( x.next() ) }" >> out.txt
I tested it both on my mac and Google cloud Ubuntu 15 with Mongo 3+.
Install MongoDB Compass, then it will have a tool to export query result to Json/CSV files.
mongoexport --host 127.0.0.1 --port 27017 --username youruser -p yourpass \
-d yourDatabaseName -c collectionName --type csv \
--fields field1,field2 -q '{"field1" : 1495730914381}' \
--out report.csv
mongoexport --db db_name --collection collection_name --csv --out file_name.csv -f field1,field2, field3
I have a simple script to get an export from MongoDB:
#!/bin/sh -x
QUERY="'{ \"type\":\"listing\" }'"
mongoexport --db event --collection listing --query $QUERY --fields type,name --csv
(I'm using the -x switch for debugging purposes)
Here's the output when I run the script:
$ ./simple_query.sh
+ QUERY='{ "type":"listing" }'
+ mongoexport --db event --collection listing --query '{ "type":"listing" }' --fields type,name --csv
ERROR: too many positional options
However, if I merely copy and paste the mongoexport line to the prompt, it works! What's going on?
(Using MongoDB 2.0.0)
Are you using older version of mongodb? If so maybe it's this bug. It is fixed on 2.0.0-* versions.
Edit: Actually this might be different problem. You can fix it by removing the spaces on the query. Spaces seem to make the shell think it is actually multiple arguments:
QUERY="'{\"type\":\"listing\"}'"
Dumped a MongoDB successfully:
$ mongodump -h ourhost.com:portnumber -d db_name01 -u username -p
I need to import or export it to a testserver and have struggle with it, please help me figure out.
I tried some ways:
$ mongoimport -h host.com:port -c dbname -d dbname_test -u username -p
connected to host.
Password: ...
Gives this error:
assertion: 9997 auth failed: { errmsg: "auth fails", ok: 0.0 }
$ mongoimport -h host.com:port -d dbname_test -u username -p
Gives this error:
no collection specified!
How to specify which collection to use? What should I use for -d? What I'd like to upload or what I want to use as test out there? I would like to import the full DB not only collection of it.
The counterpart to mongodump is mongorestore (and the counterpart to mongoimport is mongoexport) -- the major difference is in the format of the files created and understood by the tools (dump and restore read and write BSON files; export and import deal with text file formats: JSON, CSV, TSV.
If you've already run mongodump, you should have a directory named dump, with a subdirectory for each database that was dumped, and a file in those directories for each collection. You can then restore this with a command like:
mongorestore -h host.com:port -d dbname_test -u username -p password dump/dbname/
Assuming that you want to put the contents of the database dbname into a new database called dbname_test.
You may have to specify the authentication database
mongoimport -h localhost:27017 --authenticationDatabase admin -u user -p -d database -c collection --type csv --headerline --file awesomedata.csv
For anyone else might reach this question after all these years (like I did), and if you are using
a dump which was created using mongodump
and trying to restore from a dump directory
and going to be using the default port 27017
All you got to do is,
mongorestore dump/
Refer to the mongorestore doc for more info. cheers!
When you do a mongodump it will dump in a binary format. You need to use mongorestore to "import" this data.
Mongoimport is for importing data that was exported using mongoexport
