(Updated) Support Update for SharePoint Framework Field Customizers in Lists and Document Libraries [MC1094051]

Updated June 20, 2025: We will not be proceeding with this change at this time. Thank you for your patience.

We will be retiring the SharePoint Framework (SPFx) Field Customizers feature from SharePoint Lists and Document Libraries. In many cases, we recommend alternatives like using Column Formatters and disabling SPFx Field customizers. This would help with better performance with modern experience that is continuously updated.

[When this will happen:]

We are currently assessing the timelines and will update this post as plans progress. You can be assured that it will be communicated well in advance, with ample time to manage transition effectively.

[How this affects your organization:]

There is no impact to your organization as of now. In future depending on updated timelines, SharePoint Lists or Document Libraries with SPFx Field Customizers may get affected:

• Field Customizers will no longer render custom code.
• Column data will display using the default rendering based on column type.
• Other SPFx extensions, such as Command Set Customizers and Application Customizers, will continue to function as expected.

We recommend transitioning to Column Formatting for visual customizations. For scenarios requiring third-party code execution, continue using Command Set Customizers or Application Customizers.

[What you can do to prepare:]

Review your current use of Field Customizers and begin planning your transition.
