CSV is a universal plain-text data format. Converting CSV to XLS imports your data into the legacy Excel binary format, which is required by older business systems, ERP platforms, and software tools that do not support modern XLSX files.
Our CSV to XLS converter uses LibreOffice to import the CSV via the StarCalc text filter and export it using the MS Excel 97 binary writer. All rows and columns from the CSV are laid out in the resulting XLS worksheet.
XLS is still widely required by legacy financial, accounting, and industrial systems. Converting your CSV data to XLS allows you to feed data into these older tools without manual copy-paste or reformatting.
XLS is limited to 65,536 rows. Large CSV files with more rows than this limit will be truncated on conversion. For large datasets, consider converting to XLSX instead to avoid data loss.
