- Export a collection to stdout, formatted as JSON:
`mongoexport --uri={{connection_string}} --collection={{collection_name}}`

`mongoexport --db={{database_name}} --collection={{collection_name}} --query="{{query_object}}" --out={{path/to/file.json}}`
- Export documents as a JSON array instead of one object per line:
`mongoexport --collection={{collection_name}} --jsonArray`

`mongoexport --collection={{collection_name}} --type={{csv}} --fields="{{field1,field2,...}}" --out={{path/to/file.csv}}`
- Export documents that match the query in the specified file to a CSV file, omitting the list of field names on the first line:
`mongoexport --collection={{collection_name}} --type={{csv}} --fields="{{field1,field2,...}}" --queryFile={{path/to/file}} --noHeaderLine --out={{path/to/file.csv}}`
