How to Create an Org Chart from JSON
- 1
Prepare Your JSON Data
Structure your organization data as a JSON object with a root node. Each node should include a name (required), title (job position), and optionally an avatar URL. Add a children array to define subordinates beneath each person. - 2
Paste or Load Sample Data
Paste your JSON into the input editor on the left panel. If you are new to the tool, click Load Sample to see a working example of a correctly formatted organizational hierarchy that you can modify. - 3
Generate the Org Chart
Click the Generate Chart button to render your hierarchy. The tool processes the JSON instantly in your browser and displays a color-coded, multi-level organization chart in the preview panel. - 4
Export and Share
Download the finished chart as a high-resolution PNG for presentations, or copy the generated HTML to embed the org chart directly into a web page, internal wiki, or HR portal.

Why Use JSON to Org Chart?
An organization chart is one of the most common business visuals, yet most people still build them by dragging boxes in PowerPoint or paying for dedicated software. The JSON to Org Chart generator takes a different approach: you define your hierarchy as structured data, and the tool renders a professional, color-coded chart instantly in your browser. Because the input is plain JSON, it integrates easily with HR systems, employee databases, and developer workflows. You can store the data in Git, regenerate charts on demand, and maintain a single source of truth for your company structure.
The tool supports unlimited hierarchy depth, optional avatar images for each node, and automatic color assignment by level. Every chart can be downloaded as a high-resolution PNG for decks and documents, or copied as clean HTML to embed in wikis, intranets, and team pages. If you need to present the same data in different formats, pair this tool with the JSON to Chart generator for bar and pie visualizations, or the JSON to Markdown Table converter for text-based documentation.
For teams that manage organizational data programmatically, combining this tool with the JSON Formatter to validate and beautify your input, or the JSON Visualizer to explore deeply nested structures, creates a streamlined workflow from raw data to finished diagram -- all free, all running client-side with no data uploaded to any server.
How It Compares
Dedicated diagramming tools like Lucidchart, Visio, and OrgChartNow offer drag-and-drop editors and real-time collaboration, but they come with monthly subscription costs and require accounts. The FindUtils JSON to Org Chart generator is completely free, requires no signup, and processes everything in your browser. Your employee data never leaves your machine, which matters when dealing with sensitive HR information like reporting structures and personnel details.
For teams already working with structured data, the JSON-first approach is faster than manual box-and-line drawing. You can regenerate a chart in seconds after updating the source file, whereas graphical tools require manual repositioning every time someone changes roles. The trade-off is that this tool focuses on hierarchical tree layouts rather than matrix or hybrid structures -- if you need those, a full diagramming suite may be more appropriate.
