Why Is Rendering Office Documents So Hard? I Built Docxion to Find Out

Description and use

Docxion lets developers embed Office document viewing in Android and web apps without external services or licensing costs, using open source code and simple APIs.

Problem

Integrating Microsoft Office document viewing into mobile or web apps is difficult due to complex rendering stacks, proprietary SDKs, and licensing constraints.

Outcome

Docxion enables developers to embed Office document viewing with minimal effort, avoiding external services and licensing fees while providing a native‑looking API.

Workflow

• 1. Add Docxion Android library to Gradle.
• 2. Include DocxionViewer composable in UI.
• 3. Store the exposed DocxionWebViewApi via onApiCreated callback.
• 4. Call api.openFile(uri) to load a document.
• 5. Use api methods (goToPage, setZoom, search, etc.) to interact.
• 6. Handle callbacks (page change, zoom, selection) via AndroidCallbacks.
• 7. Optionally change theme or print via api.setTheme / api.print.

Evidence

Docxion is an open‑source document viewer focused on Microsoft Office formats, with an Android/Jetpack Compose integration and a reusable TypeScript/React viewer underneath.
