Built for people who live in spreadsheets
If you already track production in Excel, the add-in fits that workflow — not the other way around.
Production logs and OEE live in separate files — downtime reasons are hard to track shift to shift.
Use free OEE and Pareto in Excel, then Lean Ops Pro for structured production and downtime logs with reliability analytics.
You already work in Excel and do not want a second MES just to see OEE and losses.
Keep the workbook as the system of record. Free calculators need no login; Pro unlocks logs and analytics when you are ready.
