Excel: Automate Creator Finance Tasks

Key insights

• SharePoint Skills: No-code, reusable AI workflows saved as SKILL.md files in the site’s Agent Assets library. They capture exact steps so anyone with access runs the same process every time.
  
• Copilot in SharePoint: Create skills with natural-language chat. The AI writes the Markdown skill, and team members can invoke it by name or let the agent load relevant skills automatically.
  
• SHAREPOINT.md brain file: A grounding file that standardizes vendor terms (for example, "PO Ref" vs "Ref No.") so extraction works across variants. Use it to make multi-vendor invoice and PO extraction reliable.
  
• Finance automation example: Package four prompts into one Copilot Skill to extract invoices and POs across libraries, reconcile them, and generate a styled HTML report in one run. This replaces repetitive manual reconciliation steps.
  
• Permissions and governance: Members with edit rights can create skills; users with view rights can run them. Skills are versioned and governed by standard SharePoint controls and require the site to opt into the AI preview and Agent Assets feature.
  
• Key benefits: Eliminate repetitive work, enforce consistency and compliance, enable zero-code automation for non‑IT users, and convert individual knowledge into a shared, repeatable team asset.
  

Daniel Anderson [MVP] published a YouTube video demonstrating how finance teams can automate invoice reconciliation inside Microsoft 365 using Copilot in SharePoint. The video showcases a packaged workflow that turns multiple prompts into a reusable Copilot Skill, and it walks through the full end-to-end flow with real files. As such, the demo offers a practical look at how teams can reduce repetitive work and enforce consistency across document libraries. Consequently, it is useful for both finance practitioners and IT leaders who evaluate low-code automation options.

Video Overview and Key Demonstration

In the video, Anderson runs a reconciliation process across two SharePoint document libraries containing invoices and purchase orders. He uses a sample set of 20 invoices and 15 POs to show extraction, cross-library matching, and report generation from a single skill trigger. Moreover, the demo emphasizes that four prompts were packaged into one skill and that a grounding file named SHAREPOINT.md handles vendor terminology differences. Finally, he generates a styled HTML report to summarize reconciliation results and shows the skill running end-to-end.

How the Copilot Skill Is Built

Anderson explains that a skill lives as a Markdown file, typically called SKILL.md, inside the site’s Agent Assets library, and that the skill records a multi-step workflow for the AI to follow. He demonstrates creating prompts in the Copilot in SharePoint chat interface and packaging them into a single callable asset, which any user with view rights can run. Furthermore, the SHAREPOINT.md brain file serves as the reference dictionary that normalizes labels like "PO Ref," "Ref No.," and "Purchase Order #," which vary by vendor. Thus, the approach moves teams from repeating one-off prompts to using a standardized, reusable workflow.

Benefits and Tradeoffs

The video highlights clear benefits: automation saves time, enforces consistent checks, and reduces human error. However, Anderson also shows inherent tradeoffs, since building a robust skill requires careful setup of grounding content and prompts to avoid extraction errors. For example, while the skill automates reconciliation, it relies on accurate metadata extraction and correct permissions in SharePoint, so organizations must balance ease-of-use against the upfront effort to create and maintain the brain file. In addition, administrators must weigh governance needs, such as version control and access policies, against the productivity gains.

Technical and Operational Challenges

Anderson notes several practical challenges, beginning with vendor document variability that complicates field extraction and matching. He mitigates this with the SHAREPOINT.md brain file, but maintaining that file requires ongoing review as vendors and formats change. Moreover, OCR and parsing errors can still occur, which means teams need fallback checks or human review steps for exceptions. Finally, the feature requires site opt-in to the public preview and appropriate permissions to create or run skills, so deployment can involve coordination with site owners and IT.

Comparisons and Strategic Considerations

Compared with traditional options like Power Automate, Anderson positions SharePoint Skills as a no-code way to encode multi-step business logic directly into the collaboration layer. While Power Automate still offers deep connectors and granular control, skills emphasize repeatability and ease for non-technical users. Therefore, organizations should consider a hybrid approach: use skills for standardized, repeated processes and flows for complex integrations or advanced error handling. Also, teams must plan for maintainability so skills remain accurate as business rules evolve.

Implementation Tips and Next Steps

The video provides practical steps: extract metadata, define reconciliation logic, build a styled report, and then combine prompts into a skill file before turning it on in the site. Anderson demonstrates saving the asset into Agent Assets and running it across libraries to show consistent outcomes. Importantly, teams should pilot with a small dataset and refine the SHAREPOINT.md brain file before scaling to production. Finally, documentation and training for users who will run the skill help ensure adoption and reduce exception handling.

Overall, Daniel Anderson’s YouTube demonstration delivers a concrete playbook for automating invoice reconciliation with Copilot in SharePoint. The video balances practical tips with a clear explanation of tradeoffs, such as the effort to maintain grounding files and the need for governance. Consequently, finance teams can use the technique to eliminate repetitive tasks while planning for the operational work that keeps automations accurate. In short, the demo is a useful starting point for teams that want to convert repeatable finance workflows into reusable AI-driven assets.
