Convert presentations to structured Markdown

Slides hold a lot of structure that plain text loses. Scan Hero converts PPTX, PPT, and ODP decks into Markdown with one section per slide — diagrams and colour blocks become tables and lists, and formulas and metrics are kept intact.

Only have slide images? Export them as PNG and Scan Hero will read them with Claude Vision.

Example: Presentations → Markdown (.md)

Slides with diagrams, matrices, and formulas become structured Markdown—one section per slide, layouts and metrics preserved.

### Confusion matrix

|  | **Predicted positive** | **Predicted negative** |
|--|------------------------|------------------------|
| **Actual positive** | **True Positive [TP]** | **False Negative [FN]** *(Type 2 Error)* |
| **Actual negative** | **False Positive [FP]** *(Type 1 Error)* | **True Negative [TN]** |

### Performance metrics

| Metric | Formula |
|--------|---------|
| Sensitivity | TP / (TP + FN) |
| Specificity | TN / (TN + FP) |
| Precision | TP / (TP + FP) |
| Negative predictive value | TN / (TN + FN) |
| Accuracy | (TP + TN) / (TP + TN + FP + FN) |
Tip: One ## heading per slide. Diagrams and color blocks become tables and lists; export slide images as PNG if you only have pictures.

Frequently asked questions

How are diagrams on slides handled?

Confusion matrices, 2×2 grids, and similar diagrams are reconstructed as Markdown tables, while bullet content and formulas are preserved as lists.

Can I convert exported slide images instead of a PPTX?

Yes. Export slides as PNG or JPG and upload those; Claude Vision reads the layout and produces the same structured Markdown.
