Trust the formula,
not the saved value
Nobody re-opens every workbook to check it still calculates. FormulaLens does, in seconds, and shows you what changed.
We grade our own certainty, not your workbook’s risk.

FormulaLens does not assign a risk score. Risk depends on how the workbook is used. We report what recalculated, what diverged from the saved value, and what could not be resolved statically. Severity is yours.
