@MSC ,
If I understand correctly, you are looking at “True” or “False” values. QuickSight as today promotes them to integers and this is similar for other datasources (I tested on PostgreSQL , Athena ) ( Supported data types and values - Amazon QuickSight ) . I don’t know if this will change, but if you are looking at having “True” or “False” , you can create a calculated field ( How to create Boolean calculated field - #4 by Sanjeeb2022 )
Kind regards,
