Why Presentation Slides Confuse Standard Converters
PowerPoint and Keynote slide exports often flatten tables into isolated floating text boxes or vector shapes. Furthermore, academic slides commonly use colored cell backgrounds, dark themes, and high-contrast styling that blind legacy black-and-white OCR engines.
Tablio's multimodal vision system recognizes tabular data grids regardless of theme polarity (light or dark mode), maintaining cell relationships even when column borders are implied solely through subtle background shading.
Comparison Matrix
| Criteria | Tablio Solution | Manual / Legacy Approach |
|---|---|---|
| Dark Mode & Color Theme Support | High accuracy across all color schemes | Standard OCR fails on dark backgrounds |
| Slide Text Box Disambiguation | Separates slide headers from tabular data | Mixes slide bullet points into table cells |
| Consecutive Slide Merging | Stitches Part 1 and Part 2 slides seamlessly | Produces separate disjointed tables |
