.SH SYNOPSIS
.sp
The \fBmongoimport\fP tool provides a route to import content from a
JSON, CSV, or TSV export created by \fBmongoexport\fP, or
potentially, another third\-party export tool. See the
http://docs.mongodb.org/manual/core/import\-export document for a more in depth
usage overview, and the \fBmongoexport\fP document for more
information regarding \fBmongoexport\fP, which
provides the inverse "exporting" capability.
.SH CONSIDERATIONS
.sp
Do not use \fBmongoimport\fP and \fBmongoexport\fP for
full instance, production backups because they will not reliably capture data type
information. Use \fBmongodump\fP and \fBmongorestore\fP as
described in http://docs.mongodb.org/manual/core/backups for this kind of
functionality.
.sp
\fBmongoimport\fP is single\-threaded and inserts one document at
a time into MongoDB. Custom import tools for data ingestion may have
better performance for specific workloads.
.SH OPTIONS
.sp
Changed in version 3.0.0: \fBmongoimport\fP removed the \fB\-\-dbpath\fP as well as related
\fB\-\-directoryperdb\fP and \fB\-\-journal\fP options. You must use
\fBmongoimport\fP while connected to a \fBmongod\fP instance.

including the option multiple times, (e.g. \fB\-vvvvv\fP\&.)
.UNINDENT
.INDENT 0.0

.B \-\-host <hostname><:port>, \-h <hostname><:port>
\fIDefault\fP: localhost:27017
.sp
Specifies a resolvable hostname for the \fBmongod\fP to which to
connect. By default, the \fBmongoimport\fP attempts to connect to a MongoDB
instance running on the localhost on port number \fB27017\fP\&.
.sp
To connect to a replica set, specify the
\fBreplSetName\fP and a seed list of set members, as in
the following:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
<replSetName>/<hostname1><:port>,<hostname2><:port>,<...>

.UNINDENT

.sp
You can always connect directly to a single MongoDB instance by
specifying the host and port number directly.
.sp
Changed in version 3.0.0: If you use IPv6 and use the \fB<address>:<port>\fP format, you must
enclose the portion of an address and port combination in
brackets (e.g. \fB[<address>]\fP).

.B \-\-ssl
New in version 2.6.

.sp
Enables connection to a \fBmongod\fP or \fBmongos\fP that has

.B \-\-sslCAFile <filename>

.sp
\fBWARNING:\fP
.INDENT 7.0
.INDENT 3.5
If the \fBmongo\fP shell or any other tool that connects to
\fBmongos\fP or \fBmongod\fP is run without
\fI\-\-sslCAFile\fP, it will not attempt to validate
server certificates. This results in vulnerability to expired
\fBmongod\fP and \fBmongos\fP certificates as well as to foreign
processes posing as valid \fBmongod\fP or \fBmongos\fP
instances. Ensure that you \fIalways\fP specify the CA file against which
server certificates should be validated in cases where intrusion is a
possibility.

.B \-\-sslPEMKeyFile <filename>

.sp
Specifies the \fB\&.pem\fP file that contains both the SSL certificate
and key. Specify the file name of the \fB\&.pem\fP file using relative
or absolute paths.
.sp
This option is required when using the \fI\-\-ssl\fP option to connect
to a \fBmongod\fP or \fBmongos\fP that has
\fBCAFile\fP enabled \fIwithout\fP

.B \-\-sslPEMKeyPassword <value>
New in version 2.6.

.sp
Specifies the password to de\-crypt the certificate\-key file (i.e.
\fI\-\-sslPEMKeyFile\fP). Use the \fI\-\-sslPEMKeyPassword\fP option only if the
certificate\-key file is encrypted. In all cases, the \fBmongoimport\fP will
redact the password from all logging and reporting output.
.sp
If the private key in the PEM file is encrypted and you do not specify
the \fI\-\-sslPEMKeyPassword\fP option, the \fBmongoimport\fP will prompt for a passphrase. See
\fIssl\-certificate\-password\fP\&.

Bypasses the validation checks for server certificates and allows
the use of invalid certificates. When using the
\fBallowInvalidCertificates\fP setting, MongoDB logs as a
warning the use of the invalid certificate.
.sp

.sp
New in version 2.6: If you do not specify \fI\-\-collection\fP,
\fBmongoimport\fP takes the collection name from the input
filename. MongoDB omits the extension of the file from the
collection name, if the input file has an extension.

.B \-\-fields <field1[,field2]>, \-f <field1[,field2]>
Specify a comma separated list of field names when importing \fIcsv\fP

header) line of the file.
.sp
If you attempt to include \fI\%\-\-fields\fP when importing JSON data,
\fBmongoimport\fP will return an error. \fI\%\-\-fields\fP is only for \fIcsv\fP

As an alternative to \fI\%\-\-fields\fP, the \fI\%\-\-fieldFile\fP
option allows you to specify a file that holds a list of field names if
your \fIcsv\fP or \fItsv\fP file does not include field names in the
first line of the file (i.e. header). Place one field per line.
.sp
If you attempt to include \fI\%\-\-fieldFile\fP when importing JSON data,

but it\(aqs possible to import \fIcsv\fP and \fItsv\fP files.
.sp
The \fBcsv\fP parser accepts that data that complies with RFC
\fI\%RFC 4180\fP\&. As a result, backslashes are \fInot\fP a valid escape

If you do not specify a field or fields using the
\fI\%\-\-upsertFields\fP \fBmongoimport\fP will upsert on the
basis of the \fB_id\fP field.
.INDENT 7.0

\fI\%\-\-upsertFields\fP, which produces the same behavior.

.B \-\-upsertFields <field1[,field2]>
Specifies a list of fields for the query portion of the
\fIupsert\fP\&. Use this option if the \fB_id\fP fields in the
existing documents don\(aqt match the field in the document, but
another field or field combination can uniquely identify
documents as a basis for performing upsert operations.
.INDENT 7.0
.TP
.B \&..versionchanged:: 3.0.0
Modifies the import process to update existing objects in the

.B \-\-stopOnError
New in version 2.2.

.sp
Forces \fBmongoimport\fP to halt the import operation at the
first error rather than continuing the operation despite errors.
.sp
Changed in version 3.0.0: \fI\%\-\-stopOnError\fP interrupts the import operation when \fBmongoimport\fP encounters
an insert or upsert error. Other error types will not stop
the import.

.UNINDENT

.B \-\-jsonArray

.B \-\-maintainInsertionOrder
\fIDefault\fP: False

.SH USE
.sp
In this example, \fBmongoimport\fP imports the \fIcsv\fP
formatted data in the \fB/opt/backups/contacts.csv\fP into the
collection \fBcontacts\fP in the \fBusers\fP database on the MongoDB
instance running on the localhost port numbered
\fB27017\fP\&. \fBmongoimport\fP determines the name of files using
the first line in the CSV file, because of the \fI\-\-headerline\fP:
.INDENT 0.0
.INDENT 3.5

mongoimport \-\-db users \-\-collection contacts \-\-type csv \-\-headerline \-\-file /opt/backups/contacts.csv

.fi
.UNINDENT
.UNINDENT
.sp
Since \fBmongoimport\fP uses the input file name, without the
extension, as the collection name if \fB\-c\fP or \fB\-\-collection\fP is
unspecified. The following example is equivalent:
.INDENT 0.0
.INDENT 3.5

In the following example, \fBmongoimport\fP imports the data in

In the next example, \fBmongoimport\fP imports data from the
file \fB/opt/backups/mdb1\-examplenet.json\fP into the collection
\fBcontacts\fP within the database \fBmarketing\fP on a remote MongoDB
database. This \fBmongoimport\fP accesses the \fBmongod\fP
instance running on the host \fBmongodb1.example.net\fP over port
\fB37017\fP, which requires the username \fBuser\fP and the password
\fBpass\fP\&.

.SH TYPE FIDELITY
.sp
\fBWARNING:\fP
.INDENT 0.0
.INDENT 3.5
\fBmongoimport\fP and \fBmongoexport\fP do not reliably
preserve all rich \fIBSON\fP data types because \fIJSON\fP can
only represent a subset of the types supported by BSON. As a result,
data exported or imported with these tools may lose some measure of
fidelity. See the \fBExtended JSON\fP
reference for more information.
.UNINDENT
.UNINDENT
.sp
JSON can only represent a subset of the types supported by BSON. To
preserve type information, \fBmongoimport\fP accepts \fBstrict
mode representation\fP for certain
types.
.sp
For example, to preserve type information for BSON types
\fBdata_date\fP and \fBdata_numberlong\fP during
\fBmongoimport\fP, the data should be in strict mode
representation, as in the following:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
{ "_id" : 1, "volume" : { "$numberLong" : "2980000" }, "date" : { "$date" : "2014\-03\-13T13:47:42.483\-0400" } }
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
For the \fBdata_numberlong\fP type, \fBmongoimport\fP
converts into a float during the import.
.sp
See http://docs.mongodb.org/manual/reference/mongodb\-extended\-json for a complete list of
these types and the representations used.
