À propos de Excel to CSV Converter

The Excel to CSV Converter extracts data from Excel spreadsheets and saves it as comma-separated values (CSV) format. CSV files are universally compatible with databases, programming languages, data analysis tools, and any software that processes tabular data. Convert XLSX files to CSV for importing into MySQL, Python pandas, R, or any data pipeline.

Comment l'utiliser

  1. Upload your Excel XLSX or XLS file.
  2. Select the sheet to export (for multi-sheet workbooks).
  3. Choose the delimiter (comma, semicolon, tab) and encoding.
  4. Download the CSV file.

Formule et méthodologie

CSV format: each row on its own line, cells separated by delimiter. Values with commas or newlines: enclosed in double quotes. Double quotes inside values: escaped as two double quotes (""). Encoding: UTF-8 (recommended) or UTF-8 with BOM (for Excel compatibility). Formulas: values only (computed results), not formula expressions. Dates: formatted as strings per locale.

Cas d'usage courants

  • Importing spreadsheet data into databases (MySQL, PostgreSQL)
  • Loading Excel data into Python pandas or R for analysis
  • Providing data exports from business systems in universal format
  • Preparing data for machine learning training datasets
  • Migrating data between different software applications

Questions fréquentes

No — CSV is plain text, values only. Formatting (colors, fonts, bold), formulas (stored as computed values), merged cells, charts, and images are all lost. Multi-sheet workbooks export one sheet to one CSV file. If you need to export all sheets, convert each sheet separately. For data interchange where only values matter (which is most cases), CSV is ideal.
This is a UTF-8 BOM (byte order mark) issue. Excel expects UTF-8 with BOM to correctly identify the encoding, while most other applications prefer UTF-8 without BOM. If your CSV has non-ASCII characters (accented letters, Chinese, Arabic) and Excel shows garbled text, try saving with UTF-8 BOM. Alternatively, use Excel's "Import" function (not double-click open) and specify UTF-8 encoding manually.
