SharePoint Autofill with Power Automate

Key insights

• SharePoint Autofill columns (part of Microsoft Syntex) auto-populate file metadata but cannot update existing items in bulk.
  Nick DeCourcy’s video shows a practical workaround using a flow to force reprocessing of those items.
• Build a Power Automate flow that finds target files or list items and uses an update file properties (or update item) action to trigger Autofill processing.
  This forces Syntex to recalculate metadata without manual edits.
• Core flow structure uses dedicated triggers or a scheduled run, a query like "Get files (properties only)," and an apply to each loop to handle multiple items.
  Include conditions to skip already processed items and enable pagination for large libraries.
• Prevent loops and overload by adding a status flag column, using concurrency control, and batching requests to avoid throttling.
  These loop control and safety steps reduce repeated reprocessing and API limits.
• Automating autofill delivers clear benefits: metadata consistency, less manual work, faster approvals, and easier compliance and search.
  It also enables richer integrations with approvals, Teams, or other business systems.
• Follow best practices: test on small sets first, monitor run history, grant minimal permissions, and choose scheduled vs event-driven flows based on needs.
  For ongoing needs, design an ongoing automation (scheduled or event-based) rather than a one-off bulk run.

At a glance

In a recent you_tube_video, Nick DeCourcy (Bright Ideas Agency) examines a practical gap in SharePoint metadata management and demonstrates a workaround using Power Automate. Specifically, the video targets the limitation that Microsoft Syntex Autofill columns—available in SharePoint Premium—cannot be processed in bulk through the native UI. Consequently, organizations with large archives or many documents face manual rework when they want AI-generated metadata applied to existing items. Therefore, the video focuses on an automated flow that triggers metadata recalculation across multiple files.

First, DeCourcy credits an existing approach from consultant Leon Armston and then shows how to adapt that pattern into a repeatable flow. Next, he outlines a Power Automate flow that can batch-process items so that Autofill re-evaluates and updates metadata. Moreover, he expands the pattern to handle many files and discusses how to make the process suitable for ongoing automation rather than one-off fixes. Overall, the presentation aims to give IT teams a realistic path to scale Autofill usage without rewriting metadata by hand.

Video walkthrough: what the author shows

DeCourcy begins by framing the problem: Autofill is powerful for new files, but it offers no bulk reprocessing for existing libraries. Then, he walks viewers through the basic flow design that sequentially reads files and forces SharePoint to re-run Autofill logic. He highlights the key triggers and actions so administrators can understand what must change to trigger re-evaluation of AI-driven metadata. In addition, he explains how the pattern behaves when applied to both lists and document libraries.

After showing the basic flow, DeCourcy demonstrates ways to scale the design to handle larger sets of files without exhausting quotas. He explains options such as batching items, controlling concurrency, and adding retry logic to cope with transient errors. Moreover, he points out places where flows can pause or checkpoint so long-running operations do not time out. Finally, he summarizes possible refinements for continuous automation, rather than only running the flow as an occasional bulk job.

The video also notes practical chaptered guidance that helps viewers follow each stage: an introduction, the problem statement, the reference to Armston’s blog, the flow outline, the multi-file expansion, and a possible improved approach for ongoing needs. Consequently, viewers can jump to the segment most relevant to their situation and replicate the steps at their own pace. The narrative stays focused on real-world constraints and tradeoffs rather than promising a one-size-fits-all magic bullet. As a result, teams get both a proven pattern and a checklist of considerations to adapt it to their environment.

How the Power Automate flow works

At a technical level, the solution uses SharePoint triggers and actions to touch items so that the Autofill engine re-processes them, prompting the AI-generated fields to populate. The flow typically enumerates target files, updates a property or metadata placeholder, and then issues a second update so SharePoint runs Autofill against the item. This approach leverages the existing connectors in Power Automate and avoids custom code, which keeps complexity low and maintainability high. However, the exact actions and ordering matter, because a naive implementation can leave items only partially processed.

Moreover, the video demonstrates techniques for handling multi-file operations, such as using pagination and loop controls to avoid overwhelming the tenant. It also shows how to include logging and error capture so administrators can review which items failed and why. In addition, DeCourcy suggests performance tuning like throttling parallel runs when necessary to comply with service limits. Therefore, the flow becomes both a remediation tool and a pattern for controlled automation.

Tradeoffs and implementation challenges

While the flow solves a clear gap, it carries tradeoffs that teams must weigh. First, running bulk Autofill processing consumes API calls and can trigger throttling from the service, so administrators must balance speed against reliability. Second, the solution depends on the tenant having SharePoint Premium features enabled, which introduces licensing and cost considerations that some organizations may find restrictive. Therefore, project sponsors should evaluate the business value of updated metadata against the licensing and operational costs required to achieve it.

Additionally, the approach raises governance and security questions because the flow needs adequate permissions to read and update many items across libraries. Teams must design appropriate service accounts and consent models to minimize risk. Moreover, error handling and monitoring add operational overhead: retries, backoffs, and audit trails require careful planning to ensure the process stays transparent and recoverable. In short, the ease of building flows can mask the non-trivial operational responsibility of running them at scale.

Finally, alternative strategies may be appropriate depending on context, and the video discusses those briefly. For example, re-indexing libraries, adjusting content types, or employing hybrid reprocessing with content type hubs can sometimes reduce the need for brute-force bulk updates. In contrast, scripted or developer-led solutions may be faster in specific scenarios but introduce higher maintenance costs. Thus, teams must weigh maintainability, cost, speed, and compliance when choosing a path.

Practical recommendations for teams

If your organization plans to adopt the approach shown by DeCourcy, start small and validate outcomes before scaling. First, trial the flow on a representative library and measure the time, errors, and API usage, and then refine concurrency settings and retry policies. Next, involve compliance and security owners to confirm that automation accounts and permissions meet governance requirements. By phasing the rollout, teams can catch unexpected behaviors while keeping control of costs and impact.

Moreover, document the flow design and operational runbook so others can maintain it after initial implementation. Also, consider scheduling periodic reprocessing only when new Autofill models or extraction rules require it, rather than reprocessing continuously. Lastly, monitor tenant limits and maintain a dialogue with your platform owners so the solution remains sustainable over time. In this way, the pattern DeCourcy demonstrates becomes a repeatable, manageable technique for unlocking AI metadata in legacy content.
