Why avoid custom web parts for simple visualisations
Many teams reach for custom SharePoint web parts when they need to present data visually. A custom web part is a bespoke component developed to render data inside SharePoint pages; it can be powerful, but it also requires developer time, testing, deployment and ongoing maintenance. For many common scenarios—read‑only dashboards, cross‑list summaries and executive scorecards—organisations can build useful, secure visualisations without writing custom web parts.
Key terms defined
SharePoint list view: a built‑in presentation of a single list’s items inside SharePoint. List views are convenient but limited for cross‑list joins, aggregations and complex visuals.
Embedding: placing an externally hosted visual (for example a Power BI report) into a SharePoint or Teams page so users can view it without leaving the Microsoft 365 context.
Reporting database: a purpose‑built, queryable store (typically SQL Server) designed for analytics and reporting rather than transactional collaboration.
When list views are sufficient — and when they are not
SharePoint list views are excellent for simple, single‑list filters and groupings. They are quick to build, familiar to users and require no extra infrastructure. But list views become brittle when you need to:
- combine data from multiple lists or sites;
- join list data with records held in SQL Server or line‑of‑business systems;
- produce complex visualisations, charts or paginated reports; or
- support large datasets where performance and paging matter.
For an explanation of why SharePoint itself is not a reporting database, see this article on why SharePoint is not a reporting database and what to do instead: Why SharePoint Is Not a Reporting Database — And What to Do Instead.
Practical approaches to visualise SharePoint data without custom code
There are several low‑code or no‑code approaches that produce robust visualisations and reduce developer dependency:
1. Power BI embedded in SharePoint and Teams
Power BI is the most common choice for rich, interactive visualisations. Create a Power BI report that connects to a reporting source (more on sources below) and use the Power BI web part to embed it in SharePoint pages or add the report to a Teams channel. Embedding preserves interactivity, supports filters and respects data security when configured correctly.
2. Excel Online and Office web parts
Excel workbooks with pivot tables and charts can be stored in SharePoint and displayed using the File Viewer or Excel web part. This approach is fast for small‑to‑medium datasets and familiar to business users who already build reports in Excel.
3. Server‑side reporting and iFrames
Some organisations host paginated reports (for example SQL Server Reporting Services) or lightweight dashboards on an internal server and embed them in SharePoint via the Embed web part or an iframe. This is useful for archived or highly formatted reports that must remain read‑only.
4. Use a unified SQL repository for reliable sourcing
Many of the visualisation options above require a reliable, queryable source. Replicating SharePoint list content into SQL Server gives you richer query possibilities, predictable performance and easier joins with other systems. See the practical guide on integrating SharePoint data with line‑of‑business systems for approaches to a unified SQL repository: Integrating SharePoint data with line‑of‑business systems.
AxioWorks’ SQList is one pragmatic option organisations use to replicate SharePoint lists into SQL Server while keeping the source authoritative: https://www.axioworks.com/sqlist/.
Examples and benefits
Example 1 — Executive scorecard: load weekly snapshots of selected lists into SQL Server, build a Power BI report that calculates trends and ratios, and embed the report on an intranet page. Benefits: consistent performance, centralised refresh schedule and interactive visuals without custom front‑end code.
Example 2 — Cross‑site compliance view: replicate metadata from multiple site collections to a single SQL schema and produce a paginated report for auditors. Benefits: reliable joins across sites, ability to export to PDF and reduced load on SharePoint during report generation.
Example 3 — Lightweight departmental dashboard: store an Excel workbook in SharePoint with a data connection to SQL and present via the File Viewer web part. Benefit: minimal setup and familiar authoring experience for business users.
Performance and security considerations
When exposing SharePoint data in visualisations, consider:
- authentication and authorisation: ensure the visualisation respects user permissions. Power BI supports row‑level security; SQL sources can implement database roles and views. For context on modern authentication patterns, consult AxioWorks guidance on SharePoint authentication changes where relevant.
- data latency and refresh cadence: choose between near‑real‑time replication and periodic snapshots. Frequent refreshes increase load and complexity; less frequent snapshots reduce immediacy but simplify performance.
- surface area and least privilege: only include columns and lists required for the visualisation. Avoid publishing full lists with sensitive fields unless they are masked or excluded.
- size and query patterns: large lists should be offloaded to a reporting store. For performance best practice when working with large lists, review guidance on why large SharePoint lists can fail in production.
Reducing dependence on developers
By combining a reliable reporting source with low‑code visualisation tools, many dashboard requirements can be met by analysts and power users. Power BI Desktop, Excel and the built‑in SharePoint web parts enable business teams to assemble and embed visuals without a developer. That said, initial work to establish a secure, performant reporting store (for example a SQL Server mirror of relevant lists) may require IT involvement.
For organisations that need reliable metadata for reporting, there are established practices to extract and expose SharePoint metadata to analytics tools; a recent article outlines how unlocking SharePoint metadata supports reliable reporting: Unlocking SharePoint metadata for reliable reporting with SQList.
When this approach is appropriate — and who it is for
This approach is appropriate when you need read‑only or near‑real‑time visualisations that do not require interactive data entry inside the visual itself. Typical audiences include:
- business analysts and report authors who need to present aggregated data;
- compliance and audit teams requiring consistent exports and paginated reports;
- executive stakeholders who want single‑page dashboards accessible inside SharePoint or Teams.
It is less suitable when the visualisation must support complex transactional workflows or write‑back to SharePoint lists; those scenarios often still require custom development or dedicated application design.
Summary
Building visualisations without custom web parts reduces development time, simplifies maintenance and lets business users produce and iterate reports quickly. The reliable path combines a stable reporting store (often SQL Server) with embedding technologies such as Power BI, Excel Online or paginated reports. Where appropriate, use replication or integration patterns to centralise SharePoint data for reporting; see the article on single source of truth for additional context: Single Source of Truth: How to Build Reliable Reporting from SharePoint Data.
