Dayz Json Files -

Location: mpmissions/yourMissionName/db/

This file controls every item that spawns on your server: weapons, food, tools, clothes, and even infected loot. Each entry uses a JSON-like structure:

<type name="CanOfBeans">
    <nominal>50</nominal>
    <lifetime>3600</lifetime>
    <restock>0</restock>
    <min>10</min>
    <max>50</max>
    <value>1</value>
    <flags count_in_cargo="1" count_in_hoarder="0" count_in_map="1" count_in_player="0" crafted="0" deloot="0"/>
    <category name="food"/>
    <usage name="Industrial"/>
    <usage name="Village"/>
</type>

Editing types.xml is how you create high-tier loot zones, reduce food scarcity, or run a hardcore survival server.

If you are getting into DayZ modding, server hosting, or creating custom maps, you will quickly become intimately familiar with JSON (JavaScript Object Notation) files. DayZ relies heavily on JSON to define almost every interactive element in the game, from the loot spawning on the floor to the colors of the cars driving down the road. dayz json files

This guide breaks down what DayZ JSON files are, how they are structured, and how you can edit them to customize your server.

If you run a large community server, manually editing types.xml for 500+ items is tedious. A simple Python script can read the JSON, apply global changes (e.g., double all nominal values), and write a new file. Key tags:

Example snippet:

import json
with open('types.xml', 'r') as f:
    data = json.load(f)
for item in data['type']:
    item['nominal'] = item['nominal'] * 2
with open('types_new.xml', 'w') as f:
    json.dump(data, f, indent=2)

In the context of DayZ, JSON files are plain-text configuration files that use a structured, human-readable format to store data. Unlike the legacy .txt or .cfg files used in older Bohemia Interactive titles (like the original DayZ mod for Arma 2), JSON allows for nested data, arrays, and key-value pairs that are both easy for a human to edit and easy for the game’s engine to parse.

| Error | Likely Cause | Fix | |-------|--------------|-----| | Server won’t start | Missing comma or bracket in JSON | Validate syntax | | Items not spawning | Wrong usage name or typo | Check cfgeconomycore.xml for exact zone names | | Mod conflicting | Two JSON files editing same value | Check load order; use JSON Merge patches | | Infinite loading screen | Corrupted persistent JSON (e.g., playerdata.json) | Delete the problematic file in profiles/ |
