How to Find and Fix JSON Errors

Learn how to fix JSON syntax errors in datapacks, resource packs, and mod configs.

JSON is used in datapacks, resource packs, and some mod configurations. Even a small syntax error will prevent the file from loading.

Common JSON Mistakes

Trailing comma (most common):

{ "key1": "value1", "key2": "value2", }

Remove the comma after the last item.

Missing quotes:

{ key: "value" }

Keys must be quoted: { "key": "value" }

Single quotes:

{ 'key': 'value' }

JSON requires double quotes: { "key": "value" }

Missing brackets: Always match every { with } and every [ with ].

Fixing JSON Errors

Validate your file

Copy the file content to jsonlint.com and click Validate. It shows the exact line and error.

Fix the error

Go to Files on the XGamingServer panel, open the file, and fix the syntax.

Reload

Restart or use /reload if applicable.

💡 Tip: Use a code editor with JSON highlighting to catch errors. VS Code will underline JSON mistakes in red.
