I assume you use the SQLite database and not mySQL for the WatchedList Addon.

• Open the Database file with one of the tools described in the wiki
  
• For Windows: In SQLite DB Browser do "Database Structure" > right click on movie_watched > Export as CSV file. The Output can be processed with LibreOffice Calc or Microsoft Excel or a plain text editor
  
• For Linux: In Sqliteman enter one of the queries
  Code:

  SELECT * FROM movie_watched
  or
  Code:

  SELECT * FROM episode_watched
  and then save the output with the button "export data". This also gives you the CSV table.
  

The list of watched episodes will be connected to the list of TV shows though.
