Upload & Auto-Detect

Understanding Game Save Formats

Game developers choose save file formats based on security needs, platform requirements, and data complexity. While some formats like JSON and INI are human-readable, others like GVAS and Ruby Marshal require specialized tools to decode.

Our SaveEditor.Online uses compatibility-first parsers for selected formats and separates stable write support, limited write support, read-only inspection, and blocked exports. Uploading a file shows the detected parser and the current save capability before export.

How to Find Your Save Files

Windows: Check %APPDATA%, Documents/My Games, or the game's installation folder
macOS: Look in ~/Library/Application Support or ~/Library/Preferences
Linux: Check ~/.local/share or ~/.config
