When creating or editing a JSON or CSV file, the following limitations apply:

- Exported data is downloadable only through the user account that originally created the exported data.
- Option code must not contain a comma. The option code is specified in the format *<Option Space, Option Code>* where a comma is used as a delimiter.
- Integration between a DNS view and IP space is not supported. If there is an association between a DNS view and IP space, it will not be retained when exporting to a JSON or CSV format.
- When you export NTP configuration from the Infoblox Portal, the key value in the `ntp_keys` section is automatically removed from the exported spreadsheet as a security measure. If you later plan to import the same spreadsheet, you must add back the key value of the `ntp_keys` section to the spreadsheet before the import. Otherwise, you will encounter the following error during importing: *HTTP interceptor error: ntp key type and value must be specified*.
