.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.

holds the user\(aqs credentials.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-authenticationMechanism <name>
New in version 2.4.

.sp
Specifies the authentication mechanism. By default, the authentication
mechanism is \fBMONGODB\-CR\fP, which is the MongoDB challenge/response
authentication mechanism. In MongoDB Enterprise, \fBmongoimport\fP also includes
support for \fBGSSAPI\fP to handle Kerberos authentication. See
http://docs.mongodb.org/manual/tutorial/control\-access\-to\-mongodb\-with\-kerberos\-authentication
for more information about Kerberos authentication.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-dbpath <path>
Specifies the directory of the MongoDB data files. If used, the
\fI\-\-dbpath\fP option enables \fBmongoimport\fP to attach directly to local data
files without a running \fBmongod\fP\&. When run with \fI\-\-dbpath\fP,
\fBmongoimport\fP locks access to the data directory. No \fBmongod\fP can
access the same path while the process runs.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-directoryperdb
When used in conjunction with the corresponding option in
\fBmongod\fP, allows \fBmongoimport\fP to access data from MongoDB
instances that use an on\-disk format where every database has a distinct
directory. This option is only relevant when specifying the
\fI\-\-dbpath\fP option.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-journal
Allows \fBmongoimport\fP operations to use the durability \fIjournal\fP to
ensure data files remain valid and recoverable. This option is only
relevant when specifying the \fI\-\-dbpath\fP option.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-db <database>, \-d
Specifies the name of the database on which to run \fBmongoimport\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-collection <collection>, \-c
Specifies the collection to import.
.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.

.UNINDENT
.INDENT 0.0
.TP
.B \-\-fields <field1[,field2]>, \-f
Specify a comma separated list of field names when importing \fIcsv\fP
or \fItsv\fP files that do not have field names in the first (i.e.
header) line of the file.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-fieldFile <filename>
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.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-ignoreBlanks
Ignores empty fields in \fIcsv\fP and \fItsv\fP exports. If not
specified, \fBmongoimport\fP creates fields without values in
imported documents.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-type <json|csv|tsv>
Specifies the file type to import. The default format is \fIJSON\fP,
but it\(aqs possible to import \fIcsv\fP and \fItsv\fP files.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-file <filename>
Specifies the location and name of a file containing the data to import.
If you do not specify a file, \fBmongoimport\fP reads data from
standard input (e.g. "stdin").
.UNINDENT
.INDENT 0.0
.TP
.B \-\-drop
Modifies the import process so that the target instance drops
every collection before importing the collection from the input.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-headerline
If using \fI\-\-type csv\fP or \fI\-\-type
tsv\fP, uses the first line as field names.
Otherwise, \fBmongoimport\fP will import the first line as a
distinct document.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-upsert
Modifies the import process to update existing objects in the
database if they match an imported object, while inserting all
other objects.
.sp
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.
.UNINDENT
.INDENT 0.0
.TP
.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.
.sp
To ensure adequate performance, indexes should exist for this
field or fields.
.UNINDENT
.INDENT 0.0
.TP
.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.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-jsonArray
Accepts the import of data expressed with multiple MongoDB documents
within a single \fIJSON\fP array.
.sp
Used in conjunction with \fImongoexport \-\-jsonArray\fP to
import data written as a single \fIJSON\fP array. Limited to
imports of 16 MB or smaller.
.UNINDENT
.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\&.

Since \fBmongoimport\fP uses the input file name (minus the
extension) as the collection name if \fB\-c\fP or \fB\-\-collection\fP is
unspecified, the following example is equivalent to the previous
example:

In the next example, \fBmongoimport\fP takes data passed to it on
standard input (i.e. with a \fB|\fP pipe.)  and imports it into the
MongoDB datafiles located at \fB/srv/mongodb/\fP\&. if the import process
encounters an error, the \fBmongoimport\fP will halt because of
the \fI\-\-stopOnError\fP option.

In the final 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 http://docs.mongodb.org/manual/reference/mongodb\-extended\-json 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.
