Convert CSV to Excel (XLSX) Online

Runs 100% in your browser — your files never leave your device.

Double-clicking a CSV opens it in Excel — until a comma in a field shreds the columns. This converter builds a real .xlsx workbook from your CSV: RFC 4180 quoting, UTF-8 text, and empty cells all carry over exactly. Drop the file, download the workbook, open it anywhere spreadsheets live. Your data never leaves your device.

How it works

  1. 1

    Drop your CSV file

    Any RFC 4180 CSV works — quoted fields, embedded commas, UTF-8.

  2. 2

    Convert

    The workbook is built locally in your browser within a second.

  3. 3

    Download the XLSX

    One click saves the workbook, ready for Excel, Numbers, or Google Sheets.
