Download Game Data Editor FREE Unity. 

Game Data Editor is the complete data management package for Unity. Bring your game to life with the Intuitive and Flexible GDE Visual Data Editors or Import your data from a Spreadsheet. Using GDE’s generated data classes, accessing your data is simple, fast, and as flexible as your imagination. Do you use Playmaker? Encryption? Google Sheets? GDE has that covered and more.

GDE no longer uses PlayerPrefs! Now you can edit your saved data right in the GDE Item editor. Perfect for cheating your way to test end game content, setting up difficult to attain scenarios or balance testing.

GDE also provides a simple Random Access API. Great for any reward system i.e. determining random drops for chests, mobs, boss fights, roulette wheels, or whatever your game requires.

But don’t take my word for it. Here’s some feedback:
