Script Labs New Dawn: Officially Microsoft-Owned, Secure & Enhanced!

Key insights


  • Script Lab, a popular Office add-in for creating, running, and sharing JavaScript code snippets, is now officially maintained by Microsoft, moving away from its open-source origins.

  • The GitHub repository for Script Lab will be archived, and the add-in will no longer be open source as Microsoft takes over its development and distribution to ensure a more sustainable and secure model.

  • GitHub gist sharing functionality is being removed from Script Lab to better protect user data, affecting how users share code snippets.

  • The new version of Script Lab rolls out on April 2nd, 2024, with changes primarily affecting GitHub integration; user experience with code snippets should remain largely unchanged.

  • To recover any snippets not automatically transferred in the update, users can temporarily sideload the previous version of Script Lab until June 1st, 2024.

Understanding the Evolution of Script Lab

Script Lab, a well-regarded add-in for Office developers, facilitates the creation, execution, and sharing of JavaScript code snippets across Excel, Word, Outlook, and PowerPoint. It serves as an excellent resource for exploring the Office JavaScript API. Initially birthed as a Microsoft Garage open-source initiative, Script Lab has considerably grown.

In recognizing its expanded popularity and functionalities, Microsoft transitioned Script Lab to a protected and officially maintained format, removing its open-source status. This shift aims at crafting a more secure development environment, enhancing the Script Lab community's overall experience.

The recent strategic change entails the removal of the GitHub gist sharing feature from Script Lab to heighten security and user data protection. Although direct gist sharing is disabled, users can still share code snippets manually. The newest edition of Script Lab, deploying on April 2nd, 2024, preserves the core functionalities, ensuring a seamless user transition despite backend alterations.

  • Script Lab is now a Microsoft-only development, focusing on secure and sustainable growth.
  • The GitHub gist function is discontinued to safeguard user details and contributions.
  • Existing and new users can expect the new rollout from April 2nd, 2024, with minimal impact on their current usage.

Despite these adjustments, Microsoft remains committed to delivering a powerful tool for Office developers, acknowledging the community's feedback. The intention behind these updates is to refine and secure the user experience, promising ongoing support for Developer Tools enthusiasts. Thank you for your continued support of Script Lab.
