Synopsis¶
The bsondump converts BSON files into human-readable
formats, including JSON. For example, bsondump is useful
for reading the output files generated by mongodump.
Important
bsondump is a diagnostic tool for inspecting
BSON files, not a tool for data ingestion or other application use.
bsondump uses Extended JSON v2.0
(Canonical mode)
to format its data.
Run bsondump from the system command line, not the mongo shell.
Versioning¶
Starting with MongoDB 4.4, bsondump is now released separately
from the MongoDB Server and uses its own versioning, with an initial
version of 100.0.0. Previously, bsondump was released
alongside the MongoDB Server and used matching versioning.
For documentation on the MongoDB 4.2 or earlier versions of
bsondump, reference the MongoDB Server Documentation for that version of the tool:

This documentation is for version 100.2.1 of bsondump.

Installation¶
The bsondump tool is part of the MongoDB Database Tools package:
bsondump.Options¶
-
bsondump¶
-
--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
-vform 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¶ Validates each BSON object before outputting it in JSON format. By default, bsondump enables
--objcheck. For objects with a high degree of sub-document nesting,--objcheckcan have a small impact on performance.
-
--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 a path to a BSON file to dump to JSON.
--bsonFileis 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.
