Question 1

How do I convert Excel to CSV?

Accepted Answer

Upload your .xlsx or .xls file, choose the sheet (if there are multiple) and the delimiter (comma, semicolon or tab), and the CSV output appears instantly. Click Download to save the .csv file.

Question 2

What delimiter should I use?

Accepted Answer

Comma (,) is the standard CSV format used in the US and most English-speaking countries. Semicolon (;) is common in European locales where the comma is used as a decimal separator. Tab is useful for TSV format or pasting into spreadsheets.

Question 3

Does it handle multiple sheets?

Accepted Answer

Yes. A dropdown lets you select which worksheet to export. Each sheet is converted independently — switch between them to export different data.

Question 4

Is my Excel data safe?

Accepted Answer

Yes. The spreadsheet is parsed entirely in your browser using the SheetJS library. No file or data is ever uploaded to any server.
