Though there is a problem - the S3 connector doesn't support xlsx 😰

Hey, can you use the File connector with the S3 storage provider? https://docs.airbyte.com/integrations/sources/file/ That one supports Excel file formats (i am guessing xlsx as the default Excel file format should work)

in theory yes, but as I mentioned on the call, for csv at least the file connector in non-performant, at least for "bigish" files
