AntennaPod is a great podcast player, but you might want to migrate to another app. In order to export your data, you might try the HTML export, but that only includes a list of your subscriptions, and not the played/unplayed state of each episode.
- From Settings export the database, and then copy it to your computer
- Install sqlite, with i.e.
scoop install sqlite
- Run
sqlite3 -header -csv back.db < export.sql > export.csv
- Open
export.csv
in a CSV viewer i.e. Microsoft Excel
