|
|
|
`mongoimport --file {{path/to/file.json}} --uri {{mongodb_uri}} {{[-c|--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}} {{[-d|--db]}} {{database_name}} {{[-c|--collection]}} {{collection_name}}`
|

|
`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,...}}"`
|
