Salida — Resultados
<p><b>3 rows × 3 columns</b> → converted.xlsx (15.8 KB, from 0.0 KB of text (comma-separated, auto-detected)).</p><p style="opacity:.75">Every text cell is stored as literal text — a leading “=”, “+” or “@” cannot turn into a formula. Numbers stay exactly as pasted (no re-rounding, decimal commas are safe). Excel may show its usual “number stored as text” note — that is the fidelity choice working. Built locally with SheetJS — the text was never uploaded to a server.</p>
