A step-by-step workflow for turning old Lotus 1-2-3 archives into modern spreadsheet, archive, and analytics-ready outputs.
Identify file extensions, folder owners, years covered, and any special retention requirements before converting. Do not modify the source archive directly.
Run a small batch from each file family and review XLSX, PDF, and CSV outputs. Check dates, formulas, encoding, and any important formatting.
Use batch conversion with a dedicated output folder. Keep logs, preserve originals, and spot-check results by department, year, and extension type.
