Excel Formula FAQs
What is the difference between a formula and a function in Excel?
A formula is an expression that calculates the value of a cell, which you write yourself (e.g., =A1+B1). A function is a predefined formula that performs a specific calculation (e.g., =SUM(A1:B1)). All functions are part of formulas, but not all formulas contain functions.
How do I fix a #VALUE! error in an Excel formula?
The #VALUE! error typically occurs when your formula includes different data types, such as trying to perform a mathematical operation on a text string. To fix it, check all cells referenced in your formula to ensure they contain the correct data type (e.g., numbers for arithmetic operations).
How do I apply an Excel formula to an entire column without dragging?
You can use structured references, array formulas, or keyboard shortcuts to apply Excel formulas to entire columns automatically—saving time on large datasets.
