Upgrade to Pro

Structured Fidelity

Preserve labels, shapes, groups, relationships, and diagram direction in editable Visio objects.

Full VSDX Control

Export real editable Visio objects instead of flat images, so teams can refine, brand, annotate, and govern the diagram.

Honest Compatibility

Native diagram families receive purpose-built layouts; additional families use a documented editable-shape translation instead of a misleading flat image.

Pro

Visio → Mermaid

Reviewable Mermaid source

Recover editable Mermaid flowcharts from modern VSDX files with confidence reporting. Other Visio diagram families are detected and reported honestly instead of being flattened.
