Understanding XLS and RTF Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

Microsoft Excel 97-2003 Spreadsheet

application/vnd.ms-excel

XLS is the legacy binary spreadsheet format used by Microsoft Excel from version 97 through 2003. It stores worksheets with data, formulas, charts, and formatting in a proprietary binary structure. While superseded by XLSX, XLS files remain prevalent in legacy business systems and archives.

Advantages

  • Compatible with all versions of Microsoft Excel
  • Smaller file sizes for simple spreadsheets in some cases
  • Extensive legacy data in business and government systems

Limitations

  • Proprietary binary format that is harder to parse than XLSX
  • Row limit of 65,536 and column limit of 256
  • Vulnerable to macro-based malware and security exploits

Common Uses

  • Legacy spreadsheet archives from pre-2007 systems
  • Compatibility with older Excel-based business applications
  • Data exchange with systems that only support XLS format

Target Format

RTF E-Book

application/rtf

RTF (Rich Text Format) is occasionally used as an e-book interchange format, providing basic text formatting capabilities including fonts, bold, italic, and paragraph styling. It offers a middle ground between plain text and fully featured e-book formats, with universal readability across word processors. RTF is sometimes used as an intermediate format when converting between e-book formats.

Advantages

  • Universal compatibility with all word processors and many e-book converters
  • Supports basic formatting including fonts, styles, and paragraph layout
  • Human-readable markup that can be edited in any text editor

Limitations

  • No support for e-book-specific features like table of contents or cover art
  • Limited formatting compared to EPUB or even MOBI
  • Not recognized as an e-book format by dedicated e-reader devices

Common Uses

  • Intermediate format for e-book conversion workflows
  • Manuscript submission to some publishers and agents
  • Simple formatted e-book content for universal distribution
