How often do we migrate? How to allow only valid votes in Excel

Excel data validation gives you precise control over what values can be entered in any cell — preventing errors before they happen. By setting a permitted number range, you ensure that only realistic and relevant figures are accepted, making shared spreadsheets far more reliable. In just a few clicks via the Data tab, you can restrict cell inputs to whole numbers within a defined minimum and maximum — for example, between 3 and 12. Any value outside that range triggers an automatic error message, prompting the user to correct their entry immediately. This makes Excel data validation an especially effective tool when sharing files with others, where inconsistent or invalid inputs could otherwise skew your data.
