Power Automate Tips: Update Multi-Value Choice & Person Fields Easily

Key insights

• Power Automate is a Microsoft service that automates workflows, including updating SharePoint fields. Multi-value Choice Fields and Person Fields require special formatting as arrays to work correctly in automation flows.
  
• Multi-Value Choice Fields let users select several options from a list. In Power Automate, you must format these choices as an array of objects like {"value": "OptionName"} to update them properly.
  
• Person Fields, also called People Picker, allow multiple user selections. To update these fields, you need an array of user identifiers such as claims or emails in the required structure (for example: {"Claims": "user@domain.com"}).
  
• You can use standard Power Automate actions like “Update item” for simple updates, but for more control—such as updating only certain fields—you can send an HTTP request with a custom JSON payload formatted for multi-value choice or person fields.
  
• The main advantages include increased automation, improved precision when updating only specific fields, and greater flexibility. This makes managing SharePoint lists with multi-select fields much easier and reduces manual work.
  
• In 2025, new tutorials and resources offer best practices for handling arrays in Power Automate, clearer guidance on when to use standard actions versus HTTP requests, and updated examples for efficiently updating multi-value choice or person fields in SharePoint.
  

Introduction to Updating Multi-Value Fields in Power Automate

Updating multi-value choice or person fields in Microsoft Power Automate remains a nuanced process for SharePoint users. In a recent YouTube video, Christine Payton explores the technical challenges and solutions for efficiently handling these field types within automated workflows. As organizations increasingly rely on automation to streamline processes, understanding how to correctly format and update these fields is more important than ever.

Power Automate, as a Microsoft service, enables users to automate repetitive tasks between different applications, with SharePoint being a frequent integration point. However, multi-value fields—those that allow the selection of several choices or people—require data to be structured as arrays. This requirement can make the update process complex, especially for those new to Power Automate or SharePoint schema.

Understanding the Basics: Choice and Person Fields

In Power Automate, multi-value choice fields are used when a SharePoint list allows users to pick several predefined options. Similarly, multi-value person fields (also known as People Picker fields) permit the selection of multiple users from an organization. Both types are stored internally as arrays and must be supplied in a specific format during updates.

For example, updating a choice field requires passing an array of selected options, each wrapped in a JSON object. Person fields, on the other hand, expect an array of user identifiers—such as claims or email addresses—also formatted correctly. If these arrays are not structured as SharePoint expects, the update will fail, leading to data integrity issues.

Approaches to Field Updates: Standard Actions vs. HTTP Requests

There are two main methods for updating these fields in Power Automate. The first involves using standard actions like "Update item" or "Create item." These actions are user-friendly and ideal for straightforward scenarios where all required fields are supplied. They work well when the payload for multi-value fields is properly formatted as arrays.

However, challenges arise when updates need to be made to only a subset of fields, especially in large or complex SharePoint lists. In such cases, the HTTP request approach becomes preferable. By sending a custom HTTP request to the SharePoint REST API, users can target specific columns—including multi-value fields—without affecting mandatory fields or triggering unnecessary updates elsewhere.

This advanced method requires constructing a precise JSON payload that mirrors SharePoint’s expectations. While it offers greater flexibility and control, it also introduces complexity. Thus, users must weigh the ease of standard actions against the precision and effort required for HTTP requests.

Recent Developments and Best Practices in 2025

According to Christine Payton’s latest content, new tutorials and demonstrations have emerged to clarify best practices for handling arrays and formatting in Power Automate. These resources emphasize the importance of structuring input data correctly, whether through standard actions or HTTP requests. Additionally, community forums and updated documentation now offer more examples and streamlined methods for working with multi-select fields.

The ongoing discussion points to a tradeoff: while HTTP requests provide advanced capabilities for selective updates, they require a deeper understanding of SharePoint’s data schema. On the other hand, standard actions remain accessible but may lack the flexibility needed for certain scenarios. As automation continues to evolve, finding the right balance between simplicity and control is an ongoing challenge for Power Automate users.

Conclusion: Navigating the Challenges of Multi-Value Field Automation

In summary, updating multi-value choice or person fields in Power Automate calls for careful handling of arrays and strict adherence to SharePoint’s data formatting requirements. Users must decide between the convenience of standard actions and the granular control offered by HTTP requests, considering the specific needs of their workflow and the complexity of their SharePoint lists.

With the release of updated guides and practical demonstrations in 2025, organizations now have clearer pathways to implement effective automation. As best practices continue to evolve, staying informed about new techniques and community insights is essential for anyone looking to optimize their SharePoint integrations through Power Automate.
