what we refer to as "dynamic metadata" in CloverDX is basically a concept where the metadata structure is extracted from a result of an SQL query. In other words, the concept of dynamic metadata
(aka SQL query metadata) works with database table structures. However, there is no dynamic metadata functionality related to XLSX files. Would you mind elaborating more on how you would picture such a feature to work? Please also mention the version of CloverDX that you are currently using.
