How to Convert CSV to an Excel Workbook

Convert CSV files to XLSX when you need an Excel workbook for tables, reports, imports, or sharing data with non-technical users.

CSV is data, XLSX is a workbook

CSV stores plain table data. XLSX can open as an Excel workbook and is easier for many people to review, share, and format.

When to convert

Convert CSV to XLSX when the recipient expects Excel, when you need a workbook file, or when an import tool rejects plain CSV.

Check columns

After conversion, inspect dates, leading zeros, separators, and special characters. CSV data can be interpreted differently by spreadsheet tools.
