MS Excel: date & time function

The DATEVALUE function in Excel is designed to convert a date stored as text into a proper Excel date value. This is especially useful when importing data from external sources (like CSV files, databases, or manual entries) where dates are not always formatted correctly for calculations.

The DATE function in Excel is one of the most essential tools for anyone working with time-based data. It allows you to create a valid Excel date from three separate inputs: year, month, and day. Whether you're building financial models, automating reports, or managing timelines, the DATE function ensures accurate and consistent date creation.
