Convert Excel spreadsheets to CSV format for data import, analysis, and sharing across different systems. CSV is the universal format supported by virtually every data tool, database, and programming language.
While Excel files contain rich formatting, CSV provides a simple, lightweight format that's perfect for data transfer, database imports, and programmatic processing.
The converter processes the first worksheet in your Excel file. For multi-sheet workbooks, save each sheet separately or contact us for batch processing.
Formulas are converted to their calculated values. The CSV output contains the data results, not the formula expressions.
Excel dates are converted to a standard format in the CSV output. The exact format depends on your locale settings.
Use comma for standard CSV (most common). Use semicolon in European locales where comma is the decimal separator. Use tab when data contains commas.
