A VSCode extension built on @fefeding/ppt-parser that lets you open and edit .pptx files visually — directly inside the editor.
Features
Default .pptx handler: Double-click any .pptx in the Explorer to open it with the built-in visual editor (no extra software required).
Slide preview: Renders every slide at its original aspect ratio via pptxToHtml (most faithful). Left sidebar thumbnail navigation with zoom-to-fit and grid view.
Visual editing:
Click to select elements on the canvas; drag to move; drag handles to resize; drag the rotation grip to rotate.
Properties panel: position / size / rotation, text (content / font size / color / alignment / bold / italic / underline), shapes (fill / border), image replacement.
Insert elements: text box, rectangle, image (from local file).
Alignment / distribution / grouping / z-order / find-replace via the editor core actions.
Presentation mode: Press F5 or click "Present" for fullscreen slideshow. Navigate with arrow keys, space, or click.
Save & export: Ctrl/Cmd+S to save; "Export Copy…" to save a copy; toolbar "Discard Changes & Reload".
Undo / Redo: Ctrl/Cmd+Z, Ctrl/Cmd+Y.
Development
npm install # installs dependencies, including @fefeding/ppt-parser from npm
npm run compile # esbuild bundles dist/extension.js and dist/webview.js
npm run watch # watch mode (alias: npm run dev)
npm run package # build the production bundle and package a .vsix (vsce package)
npm run publish # publish to the VS Code Marketplace (vsce publish)
Press F5 in VSCode to launch an Extension Development Host, then open any .pptx file.
The default zoom for both preview and edit canvases is "fit to window"; use the status-bar
zoom controls (or Ctrl/Cmd + wheel on the canvas) for manual zoom.
Notes & Limitations
Editing renders straight from the editor document model provided by @fefeding/ppt-parser
(its headless editor core: createStore / docFromPptx / createActions / renderSlideInto).
On save the document is serialized back to PPTX; slide masters / layouts are rewritten to a
single blank layout. Content elements — text boxes, shapes, images, charts, tables — are
editable and preserved, and because editing renders from the model (not a byte round-trip) it
never loses fidelity such as picture or pattern fills.
The preview mode uses pptxToHtml for the most faithful rendering of the original file.
Charts are rendered with ECharts (the same renderer the parser's preview uses), including 3D
charts where supported by the source.
Complex objects such as SmartArt, OLE, and equations are retained as raw OOXML (__raw) but are
not visually editable.
