Azure Log Formatter (Beta) is a free Chrome add-on designed for users of the Azure Portal, specifically enhancing the experience with Application Insights. This tool enables developers to double-click on C# exception stack traces and JSON objects, providing a neatly formatted view of complex data structures. By simplifying the visualization of stack traces and JSON content, it aids in quicker debugging and analysis of application errors.

The functionality is straightforward: after executing a KQL query for exceptions, users can simply double-click on the relevant sections such as 'details' for stack traces or 'customDimensions' for JSON. This targeted approach allows developers to focus on their exceptions without the distraction of unformatted data, streamlining the workflow within the Azure environment.
