How VSSX to Markdown works

  1. VSSX
  2. shape text parsing
  3. pages · shapes · labels
  4. GitHub-Flavored Markdown

Built for JavaScript runtimes

Node.js

Read local files, uploads, S3/R2 objects, and other byte sources.

Cloudflare Workers

Parse Visio files directly inside Workers without Visio or a native binary.

Browser

Convert VSSX locally without uploading it to a server.

Edge

Run the same TypeScript converter in compatible Edge runtimes.

What @mdgate/visio extracts

  • Readable text from VSDX ZIP packages
  • Readable text from binary VSD OLE files
  • Shape and page text, not a visual render of the diagram

Why @mdgate/visio

Runs where your JavaScript runs

No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.

Local conversion

VSSX files can stay inside your application or browser.

Content detection

Recognizes VSSX files from their contents, not only the filename.

Deterministic parsing

The same VSSX file produces repeatable Markdown without model inference.

Small runtime surface

No Python. No native addons. No WASM. No third-party runtime dependencies.

VSSX for AI agents

Turn VSSX files into content your agent can actually work with.
