    How to use the csv to excel converter

    1. Add one or more CSV, TSV or TXT files — each becomes its own sheet.
    2. Leave the delimiter on Auto-detect or choose it yourself.
    3. Click Create Excel file to download the XLSX workbook.

    Opening a CSV directly in Excel often breaks columns, leading zeros or special characters. This converter builds a real XLSX workbook instead: it detects comma, semicolon, tab or pipe delimiters, keeps UTF-8 text intact and can turn numbers and dates into proper Excel values. Combine several CSV exports into one workbook with a sheet per file — handy for reports from shops, banks and analytics tools. Everything runs in your browser.
