Często zadawane pytania
›What delimiters are detected?
Comma (default), tab, semicolon and pipe. Auto-detected from the first line of your file.
›Are headers required?
Optional — but if your first row is headers, they become the Excel column headers (and we offer to bold them).
›Are my files uploaded?
No — conversion happens entirely in your browser via SheetJS.
›Can I convert multiple CSVs to one Excel with multiple sheets?
Currently one CSV → one sheet. Multi-sheet output is on the roadmap.
›Is the converter free?
Yes — fully free, no signup.
