The Data Validation window that pops up allows you to set your criteria in many ways. For our example, choose Whole Number for Allow:, greater than or equal to for Data:, and -700 for Minimum:.

Excel provides built-in tools to help you to find discrepancies like Filters, Conditional Formatting, advanced functions (If and IS, VLookUp, etc.), and Add-ins.

Combine an Excel custom format with data validation and remove the pressure for input perfection from personnel by letting Excel do the work.

Microsoft Excel makes it possible for users to easily get around incorrect data entries. In most cases, the user takes advantage of the data validation feature.

It’s also important to check data logic. For example, if you have ‘Start Date’ and ‘End Date’ columns, use data validation to avoid using end dates that are earlier than start dates.
