Simple Game Importer. Try to export the name of your games into a text file, paste it into SGI to add them into playnite. You can then download the metadata with playnite's built-in metadata downloader. If you want to install the games later down the line, you can use the Install Button plugin to add the game's executable exe into its entry in playnite.

I prefer things nice and simple.
