Creating Data Validation Dashboards for Teams

In this lesson, you’ll learn how to build a centralized editor dashboard that scans your entire project to report data integrity issues across all your prefabs at once.

As your project scales, opening every individual prefab to check for errors becomes impossible. Instead of hunting through folders, we can create a EditorWindow that acts as a mission control for your data. This dashboard iterates through every asset in your project—or a specific folder—and runs a suite of validation rules to flag broken references, missing required components, or invalid data ranges.

Building the Dashboard Logic

The core of a dashboard is the ability to fetch assets programmatically. We use AssetDatabase.FindAssets to locate all prefabs of a specific type and then pass them through a validator class.

// Inside an EditorWindow script
void RunValidation() {
    string[] guids = AssetDatabase.FindAssets("t:Prefab");
    foreach (string guid in guids) {
        string path = AssetDatabase.GUIDToAssetPath(guid);
        GameObject prefab = AssetDatabase.LoadAssetAtPath<GameObject>(path);
        
        // Check for missing references or invalid data
        if (IsDataInvalid(prefab)) {
            Debug.LogWarning($"Validation Error in: {path}");
        }
    }
}

By providing a UI in an EditorWindow, you can display a list of these errors as clickable items. When a developer clicks an error in your dashboard, you can use EditorGUIUtility.PingObject to highlight the specific prefab in the Project window, allowing them to fix the issue instantly.

Why Centralize Validation?

This approach shifts the responsibility of data integrity from individual manual checks to a collective team tool. Instead of waiting for a crash at runtime, your team can run the dashboard as part of their daily workflow or a CI/CD pipeline check. By visualizing the "health" of your prefabs in one view, you ensure that designers and programmers maintain high standards of data consistency without needing to understand the underlying serialization logic of every object they touch.

Key Takeaway: A Data Validation Dashboard transforms individual asset checks into a global team tool, allowing you to proactively surface and resolve structural data issues across your entire project.
