Data validation formatting refers to the process of setting rules or criteria for the data entered into a spreadsheet or database. It helps ensure that the information inputted meets specified conditions, such as numeric ranges, date formats, or predefined lists. When data is entered that doesn’t meet these criteria, it can trigger warnings or prevent the entry altogether.
For example, in a spreadsheet application like Microsoft Excel or Google Sheets, you can apply data validation to a cell or range of cells. Here are a few common types of data validation formatting:
Numeric Validation: Restricting input to specific numerical ranges (e.g., between 1 and 100) or requiring whole numbers or decimals.
Text Validation: Specifying character length limits, allowing only certain text lengths, or accepting specific text patterns (like phone numbers in a certain format).
List Validation: Creating dropdown menus or lists of acceptable entries, ensuring that users select options from a predefined set.
Date/Time Validation: Enforcing a particular date or time format (e.g., MM/DD/YYYY or DD/MM/YYYY) or restricting entries to a specific range of dates.
Custom Formula Validation: Using custom formulas or logical conditions to validate data entries. For instance, ensuring that one cell’s value is less than or equal to another cell’s value.
These validations not only help maintain data integrity but also assist users in entering accurate information by guiding them through the accepted formats or values.
In Excel or Google Sheets, you can access data validation settings through the “Data” or “Data Validation” menu options. You can then set the criteria and formatting rules for the selected cells or ranges.
