Editable output is the goal—not a misleading pixel-perfect promise. Reverse and image conversions include a review step before final delivery.

Workflow

Convert a diagram

  1. Paste or upload Mermaid source.Use plain Mermaid syntax from your documentation, backlog, or architecture notes.
  2. Run analysis.Check detected diagram type, direction, size, warnings, and blockers before generating a file.
  3. Preview the diagram.Confirm the structure visually. Public preview is processed in memory and raw source is not stored.
  4. Generate VSDX.Signed-in Basic and Pro users can generate editable Visio files within their plan limits.
  5. Open in Visio.Move, rename, restyle, and connect shapes as normal Visio objects.

Troubleshooting

Common fixes

Run Analysis first and check for missing arrows, unclosed brackets, unsupported Markdown fences, or diagram type headers such as flowchart TD, sequenceDiagram, classDiagram, erDiagram, stateDiagram-v2, or gantt.

Reduce the diagram, split it by subsystem, or use Pro access for higher node and connector limits.

Sign in before generating files. Anonymous users can preview only. If you received a Pro code, redeem it from the account page first.

These four input workflows are Pro features. Sign in with an active Pro entitlement, then reopen the converter page.

Review the generated Mermaid and preview before export. Simplify unsupported styling or correct labels and relationships.

Use a PNG exported from Draw.io with Include a copy of my diagram enabled. Mermaid2Visio recovers that embedded diagram data locally and transiently. Ordinary screenshots do not contain editable structure and remain unsupported while external vision processing is disabled.

Use a standard .drawio or mxGraph XML file. Very large, malformed, encrypted, or unsupported content is rejected safely rather than partially converted.

The generated file is intentionally editable. Use Visio alignment, themes, and connectors to refine presentation for reviews or client deliverables.

Do not paste confidential source into support. Describe the diagram type, approximate size, error text, and steps instead.
