Insurance and Actuarial Teams: Modernizing Legacy Quattro Pro Models

TL;DR

Pricing models, claims development triangles, underwriting calculators, and reinsurance schedules from the 1980s and 1990s often still live in Quattro Pro worksheets. Local conversion to XLSX, CSV, and PDF makes them reviewable in modern actuarial workflows while keeping policyholder and claims data inside the insurer's network.

Legacy actuarial models still drive present-day decisions

Loss development factors, pricing assumptions, reserve studies, and underwriting calculators created decades ago can still anchor today's rates and reserves. Many of those workbooks were originally Quattro Pro files; some were migrated to Excel decades ago, others were not.

When a regulator, reinsurer, or internal audit asks "how did we get to this number," the answer is often locked inside a workbook nobody on the current team can open natively.

What goes wrong with cloud converters in insurance

Policyholder-level data, claims notes, and pricing assumptions are exactly the data that should not be uploaded to a third-party site. Insurance regulators and reinsurance partners increasingly ask for evidence that operational data stays inside the insurer's controlled environment.

A local converter avoids the entire question: actuaries and underwriting analysts run the conversion on their own workstation and review the XLSX output without policyholder data ever leaving the firm.

Practical conversion priorities for insurers

1. XLSX for actuarial review

XLSX is the natural target. Multi-sheet workbooks, named ranges, and formulas can be inspected in Excel and re-linked into the modern modeling toolchain.

2. CSV for analytics ingestion

CSV exports of major tabs feed cleanly into reserving systems, BI dashboards, and Python/R notebooks for actuarial analytics.

3. PDF for audit evidence

PDF snapshots are how rate filings and audit responses keep "what the model looked like at this point in time" evidence. Generate them alongside the working XLSX.

What to verify after conversion

Spot-check date conventions, currency formatting, sign conventions, and a sample of formulas. Confirm hidden sheets, named ranges, and conditional formats survived the round trip into XLSX.

For audit and regulatory work, the conversion log is part of the response. Keep source paths, output paths, format, and timestamps next to the outputs.

Treat Quattro Pro archives as a one-time modernization project

Done once, with a defensible local workflow, the legacy actuarial archive becomes searchable and reviewable instead of being a quarterly fire drill. Future regulatory requests stop being a hunt for someone who remembers Quattro Pro.
