The WhatsApp backup importer plugin allows users to import exported WhatsApp chat archives into their Obsidian vault. It extracts messages from `.zip` files, processes attachments such as images and videos, and organizes the content into a specified folder. Imported chats are converted into Markdown files, with embedded links to media files for seamless navigation. Users can customize the destination folder within their vault, ensuring better organization of imported conversations. This plugin provides a structured way to store and access WhatsApp chat history within Obsidian for reference or documentation.
