Convert XLS to PDF
What is XLS?
XLS
XLS is Excel's legacy binary format using BIFF (Binary Interchange File Format) within OLE compound document structure. Stores worksheets, formulas, formatting, charts, and macros. No compression—larger files than XLSX. Maximum 65,536 rows and 256 columns per sheet. Gradually replaced by XLSX since Office 2007 but widely compatible with older systems.
- XLS is a spreadsheet format
What is PDF?
PDF stores paginated document content with fixed layouts—text, images, and vector graphics. Spreadsheets store structured data in rows and columns with formulas. While PDFs can display tables visually, they don't contain calculable cell data. Extracting tables from PDF requires specialized parsing tools, not format conversion.
- PDF preserves document structure with text, formatting, and layout information
