Question details

The user needs to automatically populate skipped survey questions with specific default answers based on the responses provided in earlier questions.

How to Set Conditional Default Answers in SharePoint Surveys

Product: SharePoint
Device & OS: not provided
Scenario: Creating a SharePoint survey where answering 'Yes' to Q1 and Q2 automatically sets the default values for Q10 through Q20 to 'Yes'.
Observed behavior: Native SharePoint surveys and Microsoft Forms branching logic only hide or show questions; they do not automatically populate conditional default values into skipped responses.

Before you start

Verify your SharePoint environment permissions and ensure you have access to Microsoft Power Automate or Power Apps, as native branching will not write data to skipped survey fields.

Solution 1Recommended

Implement Conditional Logic using Microsoft Power Automate

Since native SharePoint and Forms do not support setting conditional defaults, Power Automate provides a robust way to evaluate responses and update the dataset automatically after submission.

Branching in Microsoft Forms or SharePoint surveys is designed strictly for UI navigation (showing or hiding questions). To write actual data values into skipped fields based on previous answers, a post-submission workflow is required.

Create a Flow

Navigate to Power Automate and create an automated cloud flow triggered by 'When a new response is submitted' or 'When an item is created'.

Evaluate Conditions

Add a 'Condition' action to check if the specific answers (e.g., Q1 and Q2 are both 'Yes') meet your required criteria.

Update Survey Record

In the 'If yes' branch, add an action to 'Update item' in your SharePoint list, explicitly setting the values of the target questions (e.g., Q10 through Q20) to 'Yes'.

Calculated Fields Limit: Avoid using native SharePoint calculated fields for this purpose, as they are meant for mathematical calculations and date manipulation, not dynamic survey defaults.

Solution 2

Customize the Survey Experience with Power Apps

For a seamless user experience where defaults populate in real-time before submission, replacing the classic survey with a customized Power App is highly effective.

Frequently Asked Questions

Can I use SharePoint branching to set default answers?

No, branching in classic SharePoint surveys and Microsoft Forms is strictly used to control which questions are displayed or skipped. It does not write or populate any default data into skipped responses.

Why can't I use calculated fields for conditional survey responses?

Calculated fields in SharePoint are designed for mathematical calculations, text concatenation, or date manipulation based on other columns. They are not intended to handle dynamic conditional default values for user input during an active survey.

Is there a native Microsoft Forms feature for auto-populating answers?

Currently, Microsoft Forms does not natively support auto-populating or setting conditional default answers based on previous selections. You must rely on external automation like Power Automate to fill in this data post-submission.

How do I suggest a conditional answers feature to Microsoft?

You can submit feature requests or feedback directly through the official Microsoft SharePoint or Microsoft Forms feedback portals, allowing the development teams to consider it for future updates.
