Copy a hierarchy table directly from Excel, paste it into the grid, and convert it into editable nested PowerPoint boxes. Parent-child relationships are preserved without retyping individual labels.
Build large hierarchy diagrams without rebuilding SmartArt
Capability maps, product structures, architecture layers, taxonomies, and portfolio diagrams often begin as hierarchical spreadsheet data. Recreating a large hierarchy one box at a time in PowerPoint is slow and makes later restructuring difficult.
The Nested Block Diagram Builder groups matching levels, places fixed-width leaf boxes, and expands each parent so that its descendants remain enclosed. The layout engine uses the selected Letter, A4, or 16:9 landscape format and distributes groups across the available width to make the overall structure easier to read on one page.

Select the maximum hierarchy level used by the data. The final Text column becomes the leaf level, allowing several outputs to appear beneath the same parent.
How to generate the diagram
- Organize the hierarchy into Excel level columns and one final Text column.
- Select and copy the Excel table rows, then paste them into the Toast UI grid.
- Generate the preview and choose Letter, A4, or 16:9 landscape output.
- Generate the PPTX and adjust colors, labels, and emphasis in PowerPoint.
Designed for a complete one-page view
The goal is to show the complete structure rather than export a tall, narrow diagram. Leaf width is kept consistent while the engine determines how many groups fit across the slide. Parent boxes grow to contain the complete width and height of their children.
Frequently asked questions
Can one parent contain several final boxes?
Yes. Multiple rows may share the same parent levels while using different Text values. The final boxes are laid out inside their shared parent.
Can I copy the input table?
Yes. The grid is designed for spreadsheet copy and paste so large hierarchies can be transferred without retyping each row.
Is the PPTX a single image?
No. The exported hierarchy is built from PowerPoint shapes and text objects so the presentation can be edited after generation.
