To confirm that a range of cells all have the same value, you can use a formula based on the COUNTIF function. Formula =COUNTIF(range,”<>value”)=0 Explanation In the example shown, the formula in C9 is: =COUNTIF(C5:C8,”<>ok”)=0 Note: this formula is not case-sensitive, you can find a case-sensitive formula here. How this formula works This formula relies on… read more »
If you need to count the total number of cells in a rectangular range, you can do so with the ROWS and COLUMNS functions. Formula =ROWS(range)*COLUMNS(range) Note that this formula only works for a single rectangular range of cells. Explanation In the example, the active cell contains this formula: =ROWS(B4:C9)*COLUMNS(B4:C9) How this formula works There… read more »
If you need to count the number of columns in a range, use the COLUMNS function. COLUMNS counts the number of columns in and returns the result as a number. Formula =COLUMNS(range) Explanation In the example, the active cell contains this formula: =COLUMNS(B4:C9)
To test a range for numbers, you can use a formula based on the ISNUMBER and SUMPRODUCT functions. See example below: Formula =SUMPRODUCT(–ISNUMBER(range))>0 Explanation In the example shown, the formula in xxxx is: =SUMPRODUCT(–ISNUMBER(C5:C9))>0 How this formula works Working from the inside out, the ISNUMBER function will return TRUE when given a number and FALSE if… read more »
To verify that multiple cells have the same value with a case-sensitive formula, you can use a simple array formula based on the EXACT and AND functions. See example below: Formula {=AND(EXACT(range,value))} Explanation In the example shown, the formula in G5 is: =AND(EXACT(B5:F5,B5)) This is an array formula and must be entered with control +… read more »
To test if a range contains any values (i.e. at least one value) not in another range, you can use the SUMPRODUCT function with MATCH and ISNA. The MATCH function receives a single lookup value, and returns a single match if any. In this case, however, we are giving MATCH an array for lookup value,… read more »
To add sequential row numbers to a set of data with a formula, you can use the ROW function. See example below: Formula =ROW()-offset Explanation In the example shown, the formula in B5 is: =ROW()-4 How this formula works When not given a reference, the ROW function returns the row number of the current row…. read more »
If you need to count the number of rows in a range, use the ROWS function. The ROWS counts the number of rows in the supplied range and returns that number as the result. See illustration below: Formula =ROWS(range) Explanation In the example, the active cell contains this formula: =ROWS(B4:C9)
To confirm two ranges of the same size contain the same values, you can use a simple array formula based on the AND function. See illustration below: Formula {=AND(range1=range2)} Explanation In the example shown, the formula in C9 is: {=AND(B5:D12=F5:H12)} Note: this is an array formula and must be entered with control + shift + enter. How… read more »
To get the last relative position (i.e. last row, last column) for mixed data that may contain empty cells, you can use the MATCH function as described below. Note: this is an array formula and must be entered with Control+Shift+Enter. Formula {=MATCH(2,1/(range<>””))} Explanation In the example shown, the formula in E5 is: {=MATCH(2,1/(B4:B10<>””))} Last *relative*… read more »
