SharePoint Column Permission Solutions: Tools and WorkaroundsSharePoint does not provide native per-column permissions for list and library columns. That limitation often forces admins and site owners to look for alternative solutions when they need to hide or restrict access to sensitive column data (for example — salary, social security numbers, or personally identifiable information). This article surveys practical solutions, pros and cons, and step‑by‑step workarounds you can use depending on your environment, budget, and governance requirements.
When and why you need column-level restrictions
- Regulatory or legal requirements to limit access to specific personal or financial fields.
- Minimizing accidental exposure of sensitive information while allowing general list visibility.
- Enforcing business processes where certain roles see different data views.
Key approaches overview
- Use separate lists/libraries and link via lookup or Power Automate
- Item-level permissions (built-in SharePoint)
- Microsoft Power Apps — custom forms with role-based visibility
- Column-level encryption or data masking via Azure or third-party tools
- Third-party add-ins that provide column security
- View and page-level workarounds: audience targeting, conditional formatting, and JSON column formatting
Each approach has trade-offs in complexity, maintainability, security guarantees, and user experience. Below we examine each in detail.
Separate lists and linking (recommended for strong separation)
Concept: Move sensitive columns to a separate list with stricter permissions and link items via a lookup column or a unique ID.
How it works:
- Create two lists: MainList (general data) and SecureList (sensitive columns).
- In SecureList, include a lookup to MainList or use a shared unique identifier.
- Set permissions on SecureList so only authorized users can read items.
- Use Power Automate to create/update corresponding SecureList items when MainList changes (or vice versa).
Pros:
- Strong security boundary — SharePoint permissions apply at item level in SecureList.
- Simpler compliance: sensitive data is stored separately.
Cons: - Added complexity in data handling and UI.
- Lookups can complicate sorting, filtering, and bulk operations.
When to use:
- High-assurance environments where separating data is acceptable and integration complexity is manageable.
Item-level permissions
Concept: Use SharePoint’s item-level permissions (unique item permissions) to restrict access to specific items rather than columns.
How it works:
- Break permission inheritance on selected items.
- Assign unique permissions to groups/users for those items.
Pros:
- Native SharePoint capability.
- Fine-grained access per item.
Cons: - Not column-specific — restricts whole item.
- Performance and admin overhead if many items get unique permissions.
When to use:
- Scenarios where entire records must be restricted rather than particular fields.
Power Apps custom forms (recommended for flexible UX control)
Concept: Replace default list forms with Power Apps to control which fields different users see or can edit.
How it works:
- Customize the list form in Power Apps.
- Use Office365Users, Azure AD groups, or SharePoint groups to check the current user’s role.
- Use formula-based Visible or DisplayMode properties to hide or disable controls for unauthorized users.
Example formula to hide a control:
If(User().Email in ["[email protected]","[email protected]"], true, false) Pros:
- Great user experience; can show/hide fields dynamically.
- Works well for mobile and desktop forms.
Cons: - Security is UI-only — users with API access or list access can still see column values unless stored separately.
- Requires Power Apps licensing for some scenarios.
When to use:
- When you need tailored forms and UX rules but can accept that backend data remains accessible to those with list permissions.
JSON column and view formatting (UI hiding + conditional display)
Concept: Use SharePoint JSON formatting to hide or mask column values in list views or to show placeholders based on conditions.
How it works:
- Apply JSON formatting to a column or view to render blank/masked values unless criteria are met (for example, membership in a SharePoint group).
Pros:
- No additional services; lives in SharePoint.
- Quick to implement for visual masking.
Cons: - Only affects the rendered UI; does not prevent access via API, export, or PowerShell.
- Complex JSON needed for advanced conditions.
When to use:
- Low-risk scenarios where hiding values from casual viewers is sufficient.
Power Automate + Azure AD group checks
Concept: Use flows to control what data is written to fields or to copy sensitive data to secured locations and to log accesses.
Examples:
- On item creation, if the creator is not in a privileged group, null out a sensitive field or move it to SecureList.
- When a privileged user requests access, create a temporary view entry or copy the field to a secure location and notify auditors.
Pros:
- Automatable enforcement and auditability.
Cons: - Adds latency; complexity increases with exception paths.
When to use:
- When administrative workflows or approvals are required for sensitive data capture or disclosure.
Column-level encryption & data masking (Azure / third-party)
Concept: Encrypt specific fields in storage or apply tokenization/masking via third-party add-ons or Azure services.
Options:
- Azure Key Vault + client-side encryption.
- Third-party SharePoint add-ins that encrypt or mask columns.
Pros:
- Strong protection for data at rest and during retrieval.
Cons: - More complex architecture, potential performance impact, licensing costs, and integration work.
When to use:
- High-security environments requiring encryption at field-level with strict key management.
Third-party add-ins and tools
Examples of capabilities:
- Per-column permissions enforcement.
- Masking and conditional display.
- Auditing and reporting for column access.
Pros:
- Purpose-built; easier admin experience for column security.
Cons: - Cost, vendor lock-in, and need to evaluate trust and compliance.
When to use:
- Organizations that need out-of-the-box column security without busywork.
Page- and view-level workarounds
- Audience Targeting: show/hide web parts or pages based on audiences. Good for page-level UX separation but not for list data protection.
- Separate Views + Permissions on Pages: create pages for different roles that surface different views or web parts connected to the same list (or different lists).
- Use conditional formatting to replace values with “—” unless current user meets conditions (UI-only).
These are best for improving UX and reducing accidental exposure but do not secure backend data.
Governance, auditing, and logging
- Enforce least privilege: only give list access to users who need it.
- Use audit logs (Microsoft 365 Compliance) to track accesses and changes.
- Document design choices, retention, and backup strategies.
- Regularly review unique permissions and group memberships.
Decision guidance (summary table)
| Approach | Strong Security? | Complexity | UI Experience | Cost |
|---|---|---|---|---|
| Separate lists + lookups | High | Medium | Good (with integration) | Low–Medium |
| Item-level permissions | Medium | Medium–High | Poor (whole item restricted) | Low |
| Power Apps forms | Low (UI-only) | Medium | High | Low–Medium |
| JSON formatting | Low (UI-only) | Low | Medium | Low |
| Power Automate workflows | Medium | Medium | Medium | Low–Medium |
| Column encryption / third-party | High | High | Varies | Medium–High |
Implementation checklist (practical steps)
- Identify which columns are sensitive and why.
- Choose the minimal approach that meets security and UX needs.
- Prototype on a non-production site: test permission flows, Power Apps forms, and any automations.
- Implement logging and alerts for accesses/changes to sensitive data.
- Train users on new processes and monitor for unforeseen exposures.
Common pitfalls
- Relying on UI-only methods (Power Apps or JSON) when backend access still allows data extraction.
- Excessive unique item permissions causing list performance degradation.
- Not including auditors or compliance teams early in design.
Example: Quick Power Apps pattern to hide a field for non‑managers
- Customize form in Power Apps.
- Create an Azure AD security group “Managers”.
- Use this Visible formula on the control:
Office365Groups.IsMemberV2("group-id").value - Save and publish form.
Note: this hides the control; it does not remove the field from the list backend.
Conclusion
There’s no single perfect method because SharePoint’s permission model is not column-aware. For strong security, separate storage (different lists or encrypted fields) or third-party tools are required. For better UX with acceptable risk, Power Apps and JSON formatting provide flexible, fast solutions. Choose based on the sensitivity of data, scale, governance needs, and budget.
