--help print usage
--version print the tool version and exit verbosity options:
-v, --verbose=<level> more detailed log output (include multiple times for more verbosity, e.g. -vvvvv, or specify a numeric value, e.g. --verbose=N)
--quiet hide all log output connection options:
-h, --host=<hostname> mongodb host to connect to (setname/host1,host2 for replica sets)
--port=<port> server port (can also use --host hostname:port) ssl options:
--ssl connect to a mongod or mongos that has ssl enabled

--sslFIPSMode use FIPS mode of the installed openssl library authentication options:
-u, --username=<username> username for authentication
-p, --password=<password> password for authentication
--authenticationDatabase=<database-name> database that holds the user's credentials
--authenticationMechanism=<mechanism> authentication mechanism to use namespace options:
-d, --db=<database-name> database to use
-c, --collection=<collection-name> collection to use output options:
-f, --fields=<field>[,<field>]* comma separated list of field names (required for exporting CSV) e.g. -f "name,age"
--fieldFile=<filename> file with field names - per line
--type=<type> the output format, either json or csv (defaults to 'json') (default: json)
-o, --out=<filename> output file; if not specified, stdout is used
--jsonArray output to a JSON array rather than one object per line
--pretty output JSON formatted to be human-readable
--noHeaderLine export CSV data without a list of field names at the first line querying options:
-q, --query=<json> query filter, as a JSON string, e.g., '{x:{$gt:1}}'

几个常见的说明:

-d :数据库名
-c :表名
-o :输出的文件名
--type : 输出的格式,默认为json
-f :输出的字段,如果-type为csv,则需要加上-f "字段名"
-q:过滤条件,json字符串

举个栗子:

mongoexport -d dbname -c tablename -o filename.csv --type csv -f "column1,column2” -q '{ filtercolumn :{$gte:1,$lte:100}}'
