What is CSV to Excel?

CSV to Excel converts comma-separated values files into Microsoft Excel XLSX spreadsheets. Numbers are automatically detected and stored as numeric cells for easy sorting and calculation.

How It Works

Drop your .csv file. SheetJS parses the CSV, auto-detects numeric columns, and writes an XLSX file with a single sheet named after your file — entirely in your browser. Nothing is uploaded.

Key Benefits

  • 100% browser-based — your files never leave your device
  • Numeric values auto-detected — stored as numbers, not text
  • Sheet is named after your CSV file
  • Handles commas and quotes inside cell values (RFC 4180)
  • Free — no account or registration needed
