SharePoint Smart Org Chart & Directory vs Slack

SharePoint Smart Org Chart & Directory is a free, open-source web part that adds a searchable employee directory and interactive organization chart to a modern SharePoint page. The directory shows employee photos, names, job titles, departments, offices, email addresses, and phone numbers, with search and A–Z filtering. Chart layouts include drill-down, vertical tree, and horizontal tree views. Reporting hierarchies come from Entra ID manager and direct-report relationships through Microsoft Graph, while profile cards can display Microsoft Teams presence. Five themes, card size, sorting, visible fields, and manager levels are configurable. The interface supports 30 languages and follows each user’s Microsoft 365 language setting or the site default. Charts export to PDF or PNG, and directory data exports to Excel or CSV in the browser. The client-side web part uses delegated Graph permissions; the maker says employee data stays within the tenant. A Global or SharePoint administrator must approve User.Read.All and User.ReadBasic.All. Installation requires uploading and deploying the .sppkg package in the tenant App Catalog, then adding it to a modern page.
