Use Cases:
Ensuring that users input only numbers (e.g., product quantities, prices, scores).

How to Set Up:

Allow: Select Whole Number or Decimal.
Data: Choose conditions like "Between", "Greater than", "Less than", etc.
Enter the Minimum and Maximum values (if applicable).

Example:
You can use Data Validation to allow only decimal numbers between 0.01 and 100.00, ensuring that all entries are within this valid range.
