.nson Save Editor -

In an .nson file, a value might be stored as a String but the game expects a Float. An intelligent editor prevents type mismatches. If the field says "level": 5 (integer), the editor won’t let you accidentally type "level": "five" (string).

Some values are interdependent. Changing your level may require changing your experience points. A good .nson save editor will have a "Dependency Checker" that warns you: "Level changed to 10, but XP still matches level 1. Recalculate?"

Note: You must have a dumped NSON save file from your Nintendo Switch (requires homebrew or save management tools like JKSV).

| Feature | Description | |---------|-------------| | Automatic Parsing | Identifies NSON structure, including keys, value types (int, string, float, bool, array, object). | | Visual Editing | Provides a tree view or form-based UI for easy modification (e.g., changing Bells from 1000 to 999,999). | | Search & Replace | Locate specific keys or values across nested objects. | | Validation | Checks for data type mismatches and structural integrity before saving. | | Cross-Platform | Many NSON editors are web-based or run on Windows/macOS/Linux. | | Export/Import | Convert NSON ↔ JSON for advanced scripting or batch editing. | .nson save editor

.nson is a text-based data serialization format used by some games and applications for saving structured data (similar to JSON but with differences in syntax and data typing). A ".nson save editor" is a tool that reads, interprets, and modifies .nson-formatted save files so users can view and edit game/application state (e.g., player stats, inventory, settings).

While few tools target ".nson" exclusively, most JSON editors work perfectly. Recommended:

| Tool | Platform | Best for | |------|----------|-----------| | Visual Studio Code + "JSON Crack" extension | Win/Mac/Linux | Manual editing with schema validation | | Notepad++ with JSON Viewer plugin | Windows | Lightweight, fast | | Online JSON Editor (jsoneditoronline.org) | Web | Quick, no-install fixes | | Save Editor Universal (SEU) | Windows | Custom scripting for .nson + checksums | | jq (command line) | Cross-platform | Batch scripting (e.g., jq '.player.level = 99' save.nson > new_save.nson) | Note: You must have a dumped NSON save

⚠️ Dedicated .nson editors are rare; most games using .nson provide their own community-made tool (e.g., "Borderlands 3 .nson editor", "Hades Save Editor").

You can build a simple Python script to read/modify NSON:

import json
with open("save.nson", "r", encoding="utf-8") as f:
data = json.load(f)  # Works if NSON is JSON-compatible For binary NSON
data["player"]["health"] = 9999
with open("save_edited.nson", "w") as f:
json.dump(data, f, indent=2)

For binary NSON, look into struct or construct libraries.

Double-click the gold value. Change 150 to 10000. Ensure the editor does not add quotation marks (it should remain a number).
