About CSV to Excel

Turn a UTF8 CSV or tab separated file into an Excel XLSX workbook. Choose comma, semicolon or tab and review the table preview before saving. Every cell is stored as literal text, preserving leading zeros, date strings and formula looking values without running formulas. The workbook contains one worksheet and does not infer number types or recreate formatting.

CSV to Excel runs locally without uploading your CSV file or requiring an account. Although file selection allows up to 1 GB, available device memory can limit this particular task.
