Online file conversion

Convert XLS files for documents, editing or compatibility

XLS is the legacy Microsoft Excel workbook format based on the Binary Interchange File Format stored inside an OLE Compound File Binary container, with worksheets, formulas, formatting, and metadata encoded as binary records. Because this structure depends on older Excel-specific record handling, web upload forms, non-Excel spreadsheet tools, and document viewers may reject the file, omit features, or interpret formatting and formulas differently. Converting XLS to PDF renders the sheet layout into a fixed document for distribution, converting to XLSX translates the workbook into the newer Office Open XML structure for current spreadsheet software, and converting to CSV extracts plain tabular cell data for databases, imports, and lightweight processing.
