Preguntas frecuentes
Will quoted fields with commas inside them work?⌄
Yes — the parser understands quoted fields (e.g. "Smith, John") and doesn't split on a delimiter that's inside quotes.
What if my CSV uses semicolons instead of commas?⌄
Pick "Semicolon" from the delimiter dropdown before converting — common in several European locales' Excel exports.
Is my file uploaded?⌄
No — parsing and the .xlsx file itself are both built entirely in your browser. Your CSV never leaves your device.
Does it preserve number/date formatting?⌄
Values are written as plain text/numbers; special formatting (currency, dates) isn't inferred — reapply formatting in Excel if you need it.
