Build and navigate large org charts
Turn an existing employee list into a searchable organizational chart with hundreds or thousands of nodes. Fit ordinary charts to the screen, keep unusually wide charts readable with horizontal navigation, and focus on the branch you need.

72-node Developer Platform branch
Internally tested with a 10,000-node dataset
A large chart needs more than a bigger canvas
When every branch is squeezed into one viewport, labels and reporting lines disappear. GenerateOrgChart adapts extremely wide Fit views to preserve readable height, then lets you scroll horizontally, switch to Actual size, zoom, center, and search.

How to create a large org chart from Excel or CSV
Find anyone quickly
Search by person or role, then center and highlight the selected node without losing your current scale.
Focus on one department
Export a selected branch as PNG or SVG, or set that branch as the new root for a focused working view.
Export at useful quality
Use SVG for resolution-independent full charts. Large PNG exports automatically scale to safer browser canvas dimensions.

Built for hundreds or thousands of nodes
In internal browser-based testing, GenerateOrgChart completed import, rendering, navigation, search, and export workflows with a 10,000-node test dataset. Performance varies by chart shape, browser resources, device memory, and export format; 10,000 is a test result, not a contractual limit.
Large org chart FAQ
Can I create an org chart with thousands of employees?
Yes. Import your employee list from CSV or XLSX instead of entering each person manually. Actual performance depends on the shape of the hierarchy and your browser resources.
Why does a very wide org chart scroll in Fit mode?
Fitting every horizontal branch can make nodes too small to read. For extremely wide charts, GenerateOrgChart preserves a readable height and enables horizontal navigation.
How do I find one employee?
Open Search and enter a name or role. Selecting a result centers and highlights that node.
Can I export only one department?
Yes. Select its leader and export that branch as PNG or SVG, or set it as the active root.
Is PNG or SVG better for a large chart?
SVG is best for resolution-independent full-chart output. PNG works well for branches and is scaled when browser canvas limits require it.
