When to use CSV to Excel
Turn CSV or TSV files into a real XLSX workbook, with separate worksheets and safe text-preserving cells.
Combine three regional CSV exports into one workbook with three worksheets, preserving product codes such as 001234.
Prepare, review and export
Open one to eight CSV or TSV files and check delimiter and encoding.
Review the tables. Keep text cells for identifiers, or enable simple numeric conversion.
Download the generated XLSX workbook; each input table becomes a separate worksheet.
Limits that affect the result
5 MB combined and up to eight worksheets. Values are text by default, preserving leading zeros and long identifiers. Numeric conversion keeps leading-zero IDs and numbers longer than 14 digits as text. No macros or formulas are generated or executed.
