Convert JavaScript Alerts to Lightning Components

Now you can convert your simple JavaScript alerts to Lightning Components using the Lightning Experience Configuration Converter. For complex alerts that the tool can’t convert, such as alerts with multiple operations, the Configuration Converter recommends actions that you can take to manually convert them.

Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Professional, Performance, Unlimited, and Developer editions.

Who: The JavaScript Buttons tab requires the Customize Application and Modify All Data permissions.

The Configuration Converter is a standalone tool that lives outside of Salesforce. We recommend that you run it in a sandbox or Developer Edition org first, and then migrate your changes to your production org. To get started, visit and log in with your org credentials.
