Site Data Exporter is a Chrome add-on designed to facilitate the export and import of cookies and localStorage data for the current website. This tool ensures 100% local processing, meaning that no data is sent to external servers, thereby prioritizing user privacy. Key features include the ability to export data to a file, clipboard, or JSON box, as well as import from various sources including files and public URLs, all while maintaining CORS safety. Users can also view, edit, or delete individual cookies and localStorage entries easily.

Additionally, Site Data Exporter offers functionalities to clear site data with confirmation, preventing accidental loss of important information. The tool emphasizes security by blocking mismatched origins during import to avoid data corruption. With strict privacy measures in place, this add-on does not engage in tracking, analytics, or any third-party requests, ensuring that all operations remain within the user’s browser.
