Where and how can I extract the unique table values?

The workflow is complete. I generate unique table value sets (text values ​​with variable length rows in a column) from data stored in a table within a recursive process. During the recursion, the tables with unique value sets are created at a certain point in the process. The problem is: where and how can I extract the unique table values ​​so that I can write them to Excel?

Each table (unique value set) should be placed in the same Excel file, but on separate worksheets. The input files are placed in the table to be filtered, depending on their content (whether they contain keywords or not), and at the end of the recursion, among the unique value sets.
