Import Option: Skip Field Validation
Enabling the "Skip Field Validation" option allows you to disable validating the data you import. Warnings about phone number formats, URLs that aren't valid, etc. will not appear. Example:
With "Skip Field Validation" enabled, a new entry will be created even if an imported field contains invalid data.
Note: Validation can be disabled during the import, but Gravity Forms will still sanitize data for certain fields. For example, Gravity Forms will still strip invalid content like trying to set a number field to contain text.
