Exports VideoSaver playlists to CSV files, and converts exported CSV files back to VideoSaver playlists. This is very useful if you have large playlists and want to edit multiple items, instead of doing this via VideoSaver, just export the playlist to CSV with PlstConv and edit the CSV file in Excel or another tool for editing CSV files. After editing, you can convert the CSV file back into a VideoSaver playlist. Download: PlstConv_1.1.0_x32.zip (85 KB)
