About CKI files

A .cki file is most frequently a Cookie Clicker Save File, generated when players manually export their game progress from the popular idle game developed by Orteil. Unlike standard game saves that use binary data, these files typically contain a long, Base64-encoded text string representing your cookies, buildings, and achievements. Users often have trouble here because operating systems do not recognize the .cki extension, meaning double-clicking the file results in an "Open with..." error or a blank window. While the file itself is just a renamed text container, the proprietary encoding makes it unreadable to humans without decoding. A secondary, legacy use of this format is as a dBase Check-in File, used by the dBase database management system to track version control and file locking status in multi-user environments. For Cookie Clicker players, the goal is usually to "convert" or extract the string to import it back into the game or a save editor. For dBase users, the goal is often to convert the data to a modern structured format like CSV or SQL for archiving.

Convert.Guru analyzes your CKI file, detects the exact format, and lets you read the text inside.
