1. Microsoft Excel - Data Validation: Allow Numbers
The Data Validation - Allow Numbers feature in Microsoft Excel allows you to restrict data entry in a cell or range of cells to numeric values only. You can specify if you want whole numbers or decimal numbers, and set additional criteria like minimum and maximum values, to ensure valid and consistent data entry.

Use Cases:
Ensuring that users input only numbers (e.g., product quantities, prices, scores).
Limiting the number range to a specific interval (e.g., between 1 and 100).
Validating numeric data such as IDs, percentages, or weights.
How to Set Up:
Select the cells where you want to apply the validation.
Go to the Data tab and click Data Validation.
In the Data Validation dialog box:
Allow: Select Whole Number or Decimal.
Data: Choose conditions like "Between", "Greater than", "Less than", etc.
Enter the Minimum and Maximum values (if applicable).
Click OK to apply the validation rule.
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.

Restricting input to text-only fields like names, addresses, or product descriptions.
Ensuring that a specific text length is maintained (e.g., product codes, user IDs).
Preventing accidental entry of numbers in fields meant for text information.
