About Excel and CSV Conversion
Excel workbooks are great for formulas, multiple sheets, formatting, and analysis. CSV files are plain text, lightweight, and easy to import into databases, scripts, dashboards, and web apps. This converter helps you move between those formats without uploading files to a server.

- Formatting, colors, merged cells, charts, and multiple-sheet structure are not preserved in CSV.
- Choose semicolon or tab output when your regional spreadsheet settings expect those delimiters.
CSV to Excel Notes
- The generated workbook contains one worksheet using your chosen sheet name.
