Utilities and Energy: Preserving Compliance Spreadsheets from Lotus Archives
How regulated teams can convert operational models, rate schedules, and compliance workbooks without cloud exposure.
This guide is written for utilities, energy, and regulated operations teams who need to recover useful records from Lotus 1-2-3 spreadsheets without sending sensitive files to a cloud converter.
Regulated archives need careful handling
Historical rate models, field operations summaries, environmental reports, and engineering calculations may still exist in Lotus formats.
When those records support audits or regulatory filings, teams need local processing, stable outputs, and a clear record of what was converted.
A practical preservation set
Use PDF for a readable record, XLSX for recalculation and inspection, and CSV for importing into data warehouses. Store the conversion log next to the archive export.
Outputs to keep in the migration package
Lotus 1-2-3 Converter supports XLSX, PDF, HTML, Markdown, CSV, XLS so the same archive can serve human review, analytics import, compliance retention, and AI/RAG preparation.
Final checks before you archive the originals
Keep the original Lotus files, review a sample from each folder, and store conversion results in a separate output location. For regulated or client data, document who ran the conversion and where the resulting files were stored.
