Using SharePoint Lists with Microsoft Copilot Studio

5 minute read

SharePoint lists offer a powerful solution for businesses looking to centralize data management, streamline processes, foster collaboration, and drive productivity across various business scenarios. Over the past 2 decades, organizations have been using SharePoint to store relevant information.

This article is all about how we use SharePoint lists to find answers in Microsoft Copilot Studio. We will discuss the importance, implementation, and limitations of this approach.

SharePoint lists are super useful for businesses because they help keep things organized, make it easy for people to work together, and can be customized to fit different needs. Let’s see why SharePoint lists are so important:

1. Centralized Data Management: One big benefit of SharePoint lists is that they put all your important information in one place, making it easier to organize and manage.
2. Customization: SharePoint lists offer extensive customization options to tailor to specific business needs. Users can create custom columns, define data types, and set validation rules, allowing for the creation of highly structured and organized data.
3. Workflow Automation: SharePoint lists integrate seamlessly with Power Automate, enabling businesses to automate routine processes and streamline operations. Workflow automation can include tasks such as approval processes, notifications, and task assignments, enhancing efficiency and productivity.
4. Version Control: SharePoint lists include version control features, allowing users to track changes to list items over time.
5. Collaboration and Sharing: SharePoint lists facilitate collaboration among team members by providing real-time access to data and enabling simultaneous editing. Users can share lists with specific individuals or groups, control permissions, and track changes, promoting collaboration while maintaining data security.
6. Scalability: SharePoint lists are highly scalable and can accommodate growing data volumes and evolving business requirements. Whether managing a small team project or an enterprise-wide initiative, SharePoint lists can be scaled to meet the needs of businesses of all sizes, taking into account the threshold limits effectively.

For the demonstration purpose of this article, I have set up a SharePoint list as follows:

The schema is as follows:

The custom data source for generative answers in Microsoft Copilot Studio expects the following schema:

[
    {
        Content: "Sample content description",
        ContentLocation: "https://contoso.sharepoint.com/...",
        Title: "Contoso Sample"
    },
...
]

We will make use of Power Automate flow to generate the custom data source. This flow needs to be created and configured from the Microsoft Copilot Studio.

However, for better readability of this article, we will start with the Power Automate part first.

Part 1: Flow input

The input will be passed on from the Copilot as a user query.

Part 2: Extract the entity

Users will interact with the Copilot using natural language (e.g., tell me about remote work policy). From these queries, we need to extract the entity (e.g., remote work policy) of the user query.

Create text with GPT using a prompt:

First, we will make use of this action to extract the entity from the given prompt, generated by the GPT model.

Compose Prediction Output:

The output from the above activity will be generated in a format as follows:

{
    "extracted\_data": {
        "Policy": {
        "value": "remote work policy",
        "type": "text"
        }
    }
}

Specify the input to the activity as follows:

json(outputs('Create_text_with_GPT_using_a_prompt')?['body/responsev2/predictionOutput/text'])

Compose Entity:

To get the exact policy value from the above JSON, we will use below formula:

@{outputs('Compose_Prediction_Output')?['extracted_data']?['Policy']?['value']}

Part 3: Get and filter SharePoint list items

We will now use the Get Items activity to get the SharePoint list items and map the list columns to the schema preference of custom data supported by Copilot Studio.

We will now filter the items from the SharePoint list by comparing the title column value with the value retu
ed from the Compose Entity.

The formula is as follows:

Part 4: Retu
the output to Copilot

Let us parse the JSON first from the below sample:

[
    {
        "Title": "Remote Work Policy",
        "Content": "Establishing guidelines and expectations for employees working, including eligibility criteria, communication protocols, equipment provision, and security measures.",
        "ContentLocation": "https://www.contoso.com/remote-work-policy.html"
    }
]

Follow the below steps to set up a Copilot:

1. Navigate to Microsoft Copilot Studio at https://copilotstudio.microsoft.com.
2. Create a new Copilot named “Policy Guide”.
3. From the left menu, click Generative AI and enable the option to Boost conversational coverage with generative answers.
4. In the Instructions box provide information about how the copilot should behave or respond to users. For example: You are a policy assistant that helps people find information about organization policy.
5. Click Save.
6. Open the Conversational boosting topic.
7. Add an action to call the Power Automate flow, we created in the previous step and store the output in a variable (e.g. PolicyInformation).
8. Parse the string variable to a table (e.g. VarPolicyInformationResponse).
9. Add the Create Generative Answers node and configure the Custom data with the table variable.

Publish Copilot and test it inside the Microsoft Copilot Studio.

The Copilot experience from MS Teams is as follows:

Although this approach works, there are some limitations worth noting:

1. We can specify a maximum of 3 custom data JSON.
2. This approach still uses keyword-based search instead of vector-based search.

If you face the below error:

Error Message: The flow ‘XXXXXX’ failed to run with response code ‘BadRequest’, error code: NotSpecified. Error Code: FlowActionBadRequest

Follow the below steps to fix the issue:

1. Open the flow in Power Automate.
2. Click Details.
3. Under Run only users, click Edit.
4. Make sure all connections are configured with the Use this connection option.

Microsoft Copilot Studio does not support SharePoint lists as a data source. This limitation can be overcome by using the approach outlined in this article considering the known limitations.
