This tool converts modern Excel files (XLSX) or older XLS files into Comma Separated Values (CSV) format. CSV is a widely compatible format used for data exchange between different spreadsheet programs and databases.

• Upload your .xlsx or .xls file.
• The tool processes the first sheet in the workbook.
• A downloadable .csv file is generated, preserving the data values.

Important: Only the data from the first sheet of the Excel file will be included in the resulting CSV file. Formulas are not recalculated; only the stored values are converted.
