Häufige Fragen
What happens to multiple sheets?⌄
Each sheet becomes its own CSV file, named after the sheet, bundled into a single ZIP download.
Does it support the old .xls format?⌄
Yes — both the modern .xlsx and the legacy binary .xls format are supported.
Is my file uploaded?⌄
No — the conversion runs entirely in your browser using an on-page engine. Your spreadsheet never leaves your device.
Why choose semicolon or tab instead of comma?⌄
Some locales and tools (e.g. Excel configured for certain European regions) expect semicolon-separated values; tab-separated is handy for pasting into other apps.
