I usually create flowcharts using Mermaid, but a project I’m working on requires design documents in Excel format, which led me to start this project.

It parses Mermaid DSL and compiles it directly into Excel (.xlsx) files.

Unlike traditional tools that export diagrams as static images (PNG or SVG), mrxl translates diagram components into native Excel elements—such as shapes, cell ranges, and charts—enabling further editing and data manipulation within the spreadsheet.
