mongoimport

Imports content from a JSON, CSV, or TSV file into a MongoDB database.

• Import a JSON file into a specific collection:

mongoimport --file={path/to/file.json} --uri={mongodb_uri} --collection={collection_name}

• Import a CSV file, using the first line of the file to determine field names:

mongoimport --type={csv} --file={path/to/file.csv} --db={database_name} --collection={collection_name}

• Import a JSON array, using each element as a separate document:

mongoimport --jsonArray --file={path/to/file.json}

• Import a JSON file using a specific mode and a query to match existing documents:

mongoimport --file={path/to/file.json} --mode={delete|merge|upsert} --upsertFields="{field1,field2,...}"

• Import a CSV file, reading field names from a separate CSV file and ignoring fields with empty values:

mongoimport --type={csv} --file={path/to/file.csv} --fieldFile={path/to/field_file.csv} --ignoreBlanks

• Display help:

mongoimport --help
