Lotus 1-2-3 to PDF converter

• Lotus 1-2-3 is opened by our office engine headless and exported as PDF, prioritizing office fidelity for lotus-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.

We converted our Lotus 1-2-3 sample (151 KB) with Office engine on 2026-10-20. It took 3.6 s and produced a 143 KB PDF file, about the same size as the input. The engine raised 2 warnings, listed below.

• △Fonts that are not installed on our servers are replaced with substitutes, so lines can wrap differently.
• △Range names are not carried over; formulas use plain cell references.

The HTTP API and the MCP server run the exact engine this page uses (Office engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=lotus&to=pdf.
