By default, RPG Maker MV exports your game progress into encrypted or encoded files, typically named file1.rpgsave , config.rpgsave , or global.rpgsave . These files contain structured data tracking your inventory, character statistics, quest states, and coordinates.
General-purpose save editors (like Cheat Engine or generic hex editors) work, but they lack context. An is built specifically to parse the game's $dataMap , $gameActors , and $gameSwitches structures. Here is what you get exclusively:
Click the button. The editor will recompress the modified data and prompt you for a save location. You can overwrite the original or create a new file.

Technical Foundations: how MV saves work RPG Maker MV stores game state in JSON-based save files, usually compressed and serialized as base64 strings inside the browser-local storage or as files in desktop builds. These save files capture party state, map position, switches/variables, inventory, actor data, and plugin-related state. Because the save format is text-first and JavaScript-driven, it is unusually approachable for third-party tools: a simple parser can load JSON, present fields in a GUI, allow edits, and write a new save back in the engine’s expected structure.
They automatically pull names of items and skills directly from the game's internal database ( System.json Web-Based Access:

Many top-tier editors run in-browser (HTML5), meaning no software installation is required. Anti-Corruption Logic: By default, RPG Maker MV exports your game
The editor reads the binary .rpgsave file. If the file is encrypted (many deployed games encrypt their assets, though save encryption is less common), the editor must first decrypt it. The encryption key is typically stored in the game's www/data/System.json file under properties like hasEncryptedImages and hasEncryptedMusic .

The community has produced other specialized tools that are worth a mention:
If you want, I can:
Go to the tab to change character names, levels, or current HP.
Open the main directory of the game (where the .exe file is located). Look for a folder named . Inside the www folder, open the save directory.
Standard editors often use simplified regex patterns to find values. If a game developer used a custom plugin that stores data as a stringified object within a string, standard editors will truncate the brackets, destroying the save syntax.
