This tool converts Comma Separated Values (CSV) files into the modern Microsoft Excel format (XLSX). XLSX files support more features like formatting and formulas compared to CSV.

• Upload your .csv file.
• The tool parses the CSV data, treating the first row as headers.
• A downloadable .xlsx file is generated containing the data in 'Sheet1'.

Note: The conversion assumes a standard CSV format. Files with unusual delimiters or quoting may not parse correctly. No complex formatting is applied to the output XLSX file.
