.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.

\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

.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).

\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.

.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\&.

.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.

.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

.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:

\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.
