| Field                    | Description                                                                                                                                                                                                                                                                                                                                                         |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Type**                 | Specify the file type. The values are **CSV** (default), **JSON**, and **Avro**. You must specify the correct File type that is associated with the **Storage source URL** field in the **Setup** tab.                                                                                                                                                              |
| **Leading rows to skip** | Specify how many rows of the `CSV` file to skip.                                                                                                                                                                                                                                                                                                                    |
| **Delimiter**            | Specify the delimiter character used by the `CSV` file.                                                                                                                                                                                                                                                                                                             |
| **Quote character**      | Specify the escape (quote) character used for values that have the delimiter character in them. For example, when the delimiter character is a comma, and a field contains a comma, and the quote character is a backslash, inserting a backslash before the comma in the field will prevent that field from being evaluated as the beginning of a new field value. |
