CSV or TXT files (Max 10MB)

ℹī¸ How it works:
  • Upload your CSV (or TXT) file
  • Confirm the delimiter and encoding
  • Download a formatted Excel file instantly

Convert CSV Files to Excel Spreadsheets

Turn raw CSV data into a clean, properly formatted Excel (.xlsx) workbook. The tool auto-detects the delimiter and text encoding (so accented and international characters come through correctly), and the result has a styled, frozen header row and auto-fit column widths — ready to use in Microsoft Excel, Google Sheets, or LibreOffice Calc. No sign-up and no watermarks.

How to Convert CSV to Excel

  1. Click the upload area above or drag and drop your CSV or TXT file (up to 10 MB).
  2. The tool shows the detected delimiter and encoding — confirm them or override if needed.
  3. Convert and download your formatted .xlsx file.

Key Features

  • Auto-detect delimiter – recognizes comma, semicolon, tab, pipe or colon, with manual override
  • Auto-detect encoding – handles UTF-8, Latin-1, Windows-1252 and more, so special characters aren't garbled
  • Formatted output – the first row becomes a bold, colored header that stays frozen as you scroll
  • Auto-fit columns – column widths are sized to the content for instant readability
  • Safer spreadsheets – risky formula content (CSV injection) is blocked on upload

Common Use Cases

  • Converting database or web-app exports into Excel
  • Handing CSV reports to people who prefer Excel
  • Opening semicolon-delimited European CSVs correctly
  • Prepping CSV data for Excel formulas and charts
  • Fixing encoding problems in CSVs with special characters

Frequently Asked Questions

Excel often guesses the delimiter and encoding wrong, which leads to merged columns or garbled accented text. This tool detects them correctly and hands you a clean, formatted .xlsx so it just opens right.

No. The tool auto-detects semicolon, tab, pipe and colon delimiters as well as commas, and you can also pick the delimiter manually on the settings panel before converting.

Yes. The first row is styled as a bold, colored header and frozen in place, and every column is auto-sized to fit its content — so the spreadsheet is readable the moment you open it.
