CSV to Excel Converter

How to Convert CSV to Excel

1. Upload a .csv or .txt file, or paste the delimited text into the input box.
2. Check the preview and change the delimiter if commas, semicolons, or tabs were not detected correctly.
3. Choose a download name, then select Download Excel to create the .xlsx workbook.
4. Open the workbook and format any date, code, or identifier columns for their intended use.

Preserve Leading Zeros, Dates, and Delimiters

CSV files contain plain text rather than Excel cell types. This converter keeps parsed fields as text when it builds the workbook, so values such as 00123 are not deliberately converted to numbers during this step. Review the preview before downloading, especially when the source uses a semicolon or tab instead of a comma.

If you need Excel to interpret dates or numbers according to a particular locale, use Excel's Data → From Text/CSV import after checking the source. That workflow lets you assign a type to each column before loading it. A CSV can hold only one table of values; XLSX adds workbook features such as multiple sheets, formatting, formulas, and explicit cell types.
