Simple, grid-like tables convert well. Complex layouts with merged or multi-column cells may need a tidy-up afterwards — the tool gives you a strong starting point, not a miracle.

Scans without a text layer have nothing to extract; the tool will say so instead of making an empty file.

Each PDF page becomes its own worksheet (Page 1, Page 2, …). A single-page PDF becomes one sheet.

Cell values come through as text; Excel usually recognises plain numbers automatically, and you can format columns yourself in seconds.

No — conversion happens entirely in your browser.
