- .nson
Edit Naninovel .nson save files online. Naninovel is a Unity visual-novel engine and its saves are structured data — change variables, progress and unlocks in the browser.
Naninovel visual novels store their state in .nson save files — script variables, progress and unlocks. Upload one to browse and edit those values in the browser.
How to edit a Naninovel save
- Upload the .nson file from the game save folder.
- Search for the variable name or the current value.
- Edit it in the tree and confirm.
- Download the save and restore it to the same folder.
What you can change
- Custom script variables the novel defines
- Chapter and scene progress

Where the saves are stored
As a Unity game, Naninovel writes to the Unity persistent data path — on Windows that is %USERPROFILE%\AppData\LocalLow\<Company>\<Game>, with the saves in a "Saves" subfolder. Company and game names come from the project settings, not the store page.
What the format actually is
A .nson file is structured, JSON-shaped data: the serialized state Naninovel keeps for a slot, including the script variables the novel has set. Because it is not a binary blob, the whole save is browsable and each value can be edited in place without corrupting the file.
Questions
Is Naninovel the same as Unity?
Naninovel is a visual-novel framework for Unity, so its games are Unity builds and its saves land in the Unity persistent data folder rather than next to the executable.
Which values control the story?
Custom variables the script declares are the interesting part — they hold affection, route state and choices. They appear in the tree by name, so searching for the name is usually enough.
Can I edit the global save as well as a slot?
Yes — global saves and per-slot game saves are both .nson and both open the same way.
