COLUMNS Formula Syntax
Example Use Case
Counting the number of columns in a range for dimension analysis
Understanding the COLUMNS Formula
The COLUMNS function in Excel counts the number of columns in a specified range. It's a dimension tool for range analysis—like determining width or creating properly sized outputs based on input dimensions.
COLUMNS(A1:C10) returns 3, counting columns regardless of row count. It takes a single array or reference parameter, delivering a column count—useful for dynamic range operations or checking dimensions.
Why Use COLUMNS?
COLUMNS measures width—think range validation or dynamic outputs. Its simple count enables dimension-aware formulas, particularly valuable in array functions or when working with variable-sized data.
Example with Sample Data
| Range | Formula | Result |
|---|---|---|
| A1:C10 | =COLUMNS(A1:C10) | 3 |
| B5:B20 | =COLUMNS(B5:B20) | 1 |
| D1:H1 | =COLUMNS(D1:H1) | 5 |
COLUMNS counts width: A1:C10 spans 3 columns, D1:H1 is 5 columns wide. It's a width counter.
