Excel Formula to Check Equality

To determine if all values in the range B31:H31 are equal to the values in the range J3:J29, you can use the following Excel formula:

=AND(B31=J3, B31=J4, B31=J5, B31=J6, B31=J7, B31=J8, B31=J9, B31=J10, B31=J11, B31=J12, B31=J13, B31=J14, B31=J15, B31=J16, B31=J17, B31=J18, B31=J19, B31=J20, B31=J21, B31=J22, B31=J23, B31=J24, B31=J25, B31=J26, B31=J27, B31=J28, B31=J29)

Explanation

Function Used:
- AND: This function checks if all conditions within it are TRUE. If all conditions are TRUE, it returns TRUE; otherwise, it returns FALSE.
Logic:
- The formula compares the value in B31 with each value in the range J3:J29.
- It checks if B31 matches all values in the J column range (from J3 to J29). If any value does not match, the result will be FALSE.
Scope:
- This formula will yield TRUE if every cell in the column J (J3 to J29) is equal to the value in B31. If any are not equal, the result will be FALSE.

Practical Illustration

Assume the following values:

B31 = 10
J3 = 10
J4 = 10
...
J29 = 10

In this example, the formula will return TRUE, as all comparisons are satisfied (B31 equals each of the values in the J column).

Conversely, if B31 = 10 and one of the J column cells, say J3, contains the value 20, the formula will return FALSE, indicating that not all values are equal.

Alternative Approach (Using a Helper Column)

If you need to compare multiple cells dynamically without writing a long AND statement, consider using a helper column:

Place this formula in any cell in the range J to check equality of values in B31 and each J cell:

=IF(B31=J3, TRUE, FALSE)

Drag the formula down from J3 to J29. This will generate TRUE or FALSE in the helper column for each comparison.
Finally, check if all values in the helper column are TRUE:

=AND(J3:J29)

This formula will give a single TRUE or FALSE output, depending on whether all J values match B31.

Conclusion

The direct formula provided initially allows for a straightforward comparison.
Alternatively, using a helper column provides flexibility and dynamic comparison capabilities.
Both methods ensure that the user can effectively ascertain the equality across the specified ranges in Excel.
