New in version 12.3: The TCA field type json has been added to TYPO3 Core.

When using the json type, TYPO3 takes care of generating the according database field. A developer does not need to define this field in an extension's ext_tables.sql file.


Currently, we have not documented this TCA type in detail. In the meantime, you can find more information in the according changelog. If you can help us with setting up the documentation for this type, please provide a pull request.
