What changes

  • Microsoft Works Spreadsheet is opened by our office engine headless and exported as PDF, prioritizing office fidelity for wks-to-pdf.
  • Paragraph styles, tables, images, headers, footers, and page breaks are preserved when our office engine can map them.
  • Macros, scripts, document automation, and active form behaviour are not executed or preserved in the output.
  • Missing fonts are substituted by server fonts, so line breaks and pagination can shift from the authoring machine.
  • Tracked changes are accepted as the visible document state; reviewer comments may not appear unless they are visible in the exported view.
  • Our office engine can produce PDF output, but this service does not expose a PDF/A conformance switch in content options.
