Free tool
Paste Mermaid flowchart syntax and get back an editable .drawio file, the same XML format Lucidchart and draw.io both read, plus a live preview of the diagram as you type. Runs entirely in your browser; nothing is uploaded anywhere. Built by Imran Anwar, Principal Workday Integration Consultant.
v1 scope: flowcharts only (graph / flowchart with TD, LR, RL, BT). Supports rectangle, rounded, diamond, and circle node shapes, plain/dotted/thick edges, and |label| edge labels. Subgraphs, sequence diagrams, class diagrams, and other Mermaid types aren’t converted yet.
Layout is auto-generated (ranked left-to-right or top-to-bottom by dependency order), so re-arrange nodes freely once you’re in Lucidchart or draw.io. Treat this as a fast first draft, not final positioning.
