範例
Paste CSV (or TSV / semicolon / pipe text) — the workbook is built locally with SheetJS; nothing is uploaded.
輸入
name,qty,price widget,3,"12,50 €" gadget,7,9.99
輸出 — 搜尋結果
<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>
執行
說明
Paste CSV, TSV, semicolon or pipe text and download a real .xlsx — quotes, CRLF and UTF-8 handled, delimiters auto-sniffed (TAB ; , |) or set by hand, decimal commas preserved, nothing uploaded.
