bsondump

Synopsis

bsondump converts BSON files into human-readable formats, including JSON. For example, bsondump is useful for reading the output files generated by mongodump.

bsondump uses Extended JSON v2.0 (Canonical mode) to format its data.

Run bsondump from the system command line, not the mongo shell.

Options

--help

Returns information on the options and use of bsondump.

--verbose, -v

Increases the amount of internal reporting returned on standard output or in log files. Increase the verbosity with the -v form by including the option multiple times, (e.g. -vvvvv.)

--quiet

Runs bsondump in a quiet mode that attempts to limit the amount of output.

This option suppresses:

• output from database commands

• replication activity

• connection accepted events

• connection closed events

--version

Returns the bsondump release number.

--objcheck

Deprecated since version 9.0. :

Validates each BSON object before outputting it in JSON format. By default, bsondump enables --objcheck <bsondump --objcheck>. For objects with a high degree of sub-document nesting, --objcheck <bsondump --objcheck> can have a small impact on performance.

Starting in MongoDB 9.0, this option has no effect on server behavior. bsondump always validates BSON objects.

--type=<json|debug>

Changes the operation of bsondump from outputting JSON (the default) to a debugging format.

--pretty

Outputs documents in a pretty-printed format JSON.

--bsonFile

Specifies the path to a BSON file to dump to JSON. --bsonFile is an alternative to the positional \<bsonFilename\> option.

By default, bsondump reads from standard input.

<bsonFilename>

The final argument to bsondump is a document containing BSON. This data is typically generated by bsondump or by MongoDB in a rollback operation.

--outFile=<file>

Specifies the path of the file to which bsondump should write its output JSON data.

By default, bsondump writes to standard output.
