Overview

The HTML Viewer is a custom Power BI visual that lets you render HTML content directly in your reports. It enables flexible formatting and enhanced data presentation using standard HTML, while ensuring safe rendering through built-in sanitisation.

Key Features

     ○ Render HTML content from your dataset

     ○ Support for formatted text, tables, lists, and links

     ○ Multiple display modes: HTML, Raw Text, and Debug

     ○ Built-in HTML sanitisation for safe rendering

     ○ Optional support for external images

     ○ Lightweight and optimised for performance

How it works

The visual reads HTML content from your data model and renders it inside the Power BI report canvas.
All processing happens locally within the Power BI visual environment.

HTML Handling & Security

The visual sanitises all HTML content before rendering it to ensure safe and consistent display.

Only the following HTML tags are supported:

h1, h2, h3, h4, h5, h6,
p, br, hr, span, div,

strong, b, em, i, u, s, sub, sup,
ul, ol, li,

table, thead, tbody, tfoot, tr, th, td,
a, img,

pre, code, blockquote,
style

All other HTML tags are removed during sanitisation and will not be rendered.

     ○ Links can be opened by the user

     ○ External images are blocked by default and can be enabled in the visual settings

     ○ Rendering is subject to Power BI sandbox restrictions

Display Modes
