Step-by-step explanation:
The feature that examines the formulas in a workbook in a manner similar to how the spell checker examines a workbook for misspelled words is Formula Auditing. Tools within this feature, like the Formula Evaluator or Error Checking, help identify errors in cell calculations and can trace cell references to ensure formulas are working correctly.
