# Dataverse ERD

Power DevBox Dataverse ERD is a Chrome and Microsoft Edge extension that turns a Microsoft Dataverse solution into an **entity-relationship diagram (ERD)** and a table-design document. Use it to understand custom lookup relationships, identify related tables outside your solution, and prepare technical documentation without exporting a solution ZIP.

| [Create a diagram](/dev-tools/chrome-extensions/dataverse-erd/getting-started.md)               | Choose a visible solution in your signed-in Dataverse environment.                                 |
| [Read the ERD](/dev-tools/chrome-extensions/dataverse-erd/diagram.md)                           | Follow custom lookup relationships and distinguish solution tables from external dependencies.     |

| [Copy Markdown](/dev-tools/chrome-extensions/dataverse-erd/exports.md#copy-markdown)            | Paste a field catalogue into a Markdown document.                                                  |
| [Download Excel](/dev-tools/chrome-extensions/dataverse-erd/exports.md#table-design-excel)      | Review table and column descriptions, lookup targets and choice details in a filterable worksheet. |
| [Save SVG or PNG](/dev-tools/chrome-extensions/dataverse-erd/exports.md#diagram-images)         | Include a diagram in a design document or presentation.                                            |
| [Export role permissions](/dev-tools/chrome-extensions/dataverse-erd/exports/security-roles.md) | Review table privileges for security roles included in the selected solution.                      |

## How it connects

The extension uses the authorization token from your existing signed-in Power Platform or Dynamics browser session. It reads Dataverse metadata directly and renders the diagram and exports in your browser. You do not enter a password, paste a token or configure a separate backend.

You still need access to the environment and permission to read the relevant metadata. See [Permissions and data handling](/dev-tools/chrome-extensions/dataverse-erd/permissions-and-data.md) before installing on a managed device.

{% hint style="info" %}
**A focused view, not a complete schema audit.** The diagram shows custom lookup relationships, not every standard relationship or many-to-many relationship. The field catalogue is also scoped, rather than a dump of every system column. Read [Diagram and Mermaid](/dev-tools/chrome-extensions/dataverse-erd/diagram.md) and [Exports](/dev-tools/chrome-extensions/dataverse-erd/exports.md) for the exact coverage.
