: For custom loadout editing, tools like DayZ Loadout JSON Processor can help adjust ammo quantities and manage config files effectively.
Below I analyze typical sources, file types, structure patterns, uses, tools that generate/consume them, common fields and schemas, pitfalls, and practical steps to inspect, validate, and reuse DayZ JSON files.
Creating a "Trader City spawn" or restricting spawns to a specific faction territory. 2. cfggameplay.json
Text strings require quotation marks ( "true" ), while numbers ( 5.0 ) and booleans ( true / false ) do not. dayz json files
The most critical JSON file is cfggameplay.json , which acts as the "master" file for gameplay modifications.
Most owners use the DayZ Editor to visually place items and then export them as a JSON.
When running multiple mods, JSON conflicts occur if two mods define the same object. The matters. DayZ will merge arrays but may overwrite objects. Use a tool like DayZ Mod Merger (GitHub) to intelligently combine types.xml from different mods. : For custom loadout editing, tools like DayZ
Before your server can read custom JSON files, you must enable the feature in your main server configuration. : This is your main server config file.
DayZ files are strictly case-sensitive. If an item class name is M4A1 , writing m4a1 inside a JSON configuration will cause the server to fail to recognize the item, resulting in errors or missing assets. 5. Troubleshooting Common JSON Errors
JSON files are text-based files used to store structured data in a human-readable format. DayZ uses them alongside XML files to manage server infrastructure. While XML generally handles the central economy (like item spawning rules), JSON files typically handle gameplay mechanics, player data, mod configurations, and administrative tools. Why JSON Matters Easy for humans to read and machines to parse. Most owners use the DayZ Editor to visually
Defining custom zombie spawns, weather patterns, and event schedules.
Let’s explore the essential JSON files you will encounter. These are typically found inside your mission folder (e.g., mpmissions\yourMission\ ).
Below, we’ll break down everything you need to know—from core server configs to advanced types.xml editing.
Never edit files directly inside the DayZ installation folder if you play on official public servers. The anti-cheat (BattlEye) may flag modified core files. Always use a mission folder or mod folder for changes.
These are typically located in a directory called profiles or config on your server host (e.g., Nitrado, GTX Gaming, or a local VPS). Common Modded JSON Structures:
