CSV to Excel Converter
How it works
This tool reads your CSV locally, parses rows and columns, and then generates an Excel (.xlsx) file using SheetJS. It works well for exports from databases, portals, and reporting systems, including Italian datasets that often use semicolon delimiters.
- Use Auto-detect first; switch delimiter if columns look wrong.
- Large CSV files can take longer to parse — consider filtering rows before converting.
- Your data stays in the browser. No upload is required.
