To find the longest string in a range with criteria, you can use an array formula based on INDEX, MATCH, LEN and MAX. In the example shown, the formula in F6 is:
{=INDEX(names,MATCH(MAX(LEN(names)*(class=F5)),LEN(...

To test if a numeric value falls between two numbers, you can use the AND function with two logical tests. In the example shown, the formula in E5 is:
=AND(D5>MIN(B5,C5),D5<MAX(B5,C5))
How this formula works...

To look up the maximum value in a range based on specific critieria, you can use a basic array formula based on the IF function.
Example data and problem
In the example shown, we have almost 10,000 rows of data. The...

To get the larger, or greater, of two values, you can use the MAX function. In the example shown, the formula in D5 is:
=MAX(B5,C5)
How this formula works
The MAX function is fully automatic – it returns the largest...

To calculate the longest winning streak, you can use an array formula based on the frequency function.
Note: FREQUENCY must be entered as an array formula using Control + Shift + Enter

To get the position of the last match (i.e. last occurrence) of a lookup value, you can use an array formula based on the IF, ROW, INDEX, MATCH, and MAX functions. In the example shown, the formula in H6 is:
{=MAX(IF(...

To get the maximum value in a data set based on more than one criteria, you can use an array formula based on the MAX and IF functions. In the example shown, the formula in I6 is:
{=MAX(IF(color=G6,IF(item=H6,price...

To extract a word that contains specific text,you can use a formula based on several functions, including TRIM, LEFT, SUBSTITUTE, MID, MAX, and REPT. You can use this formula to extract things like email addresses, or...

To calculate the max or min change in a set of data as shown, without using a helper column, you can use an array formula. In the example, the formula in G6 is:
{=MAX(C5:C12-D5:D12)}
Note: this is an array formula...

To get the maximum value from a set of numbers, use the MAX function.
In the example shown, the formula in cell I6 is:
=MAX(C6:G6)
The MAX function is fully automatic. It accepts one or more arguments, which can be...

To calculate gas (MPG) based on odometer readings you can build a table with a few simple formulas. In the example shown, the formulas in E5 and F5 are:
=[@Mileage]-SUM(C4) // E5 calculate mileage
=[@Distance]/[@...

To get the max of every nth column, you can use an array formula based on the MAX, MOD, and COLUMN functions. In the example shown, the formula in M5 is:
=MAX(IF(MOD(COLUMN(B5:K5)-COLUMN(B5)+1,L5)=0,B5:K5))
Note:...

To find the position (row) of the last file revision in a table, you can use a formula based on several Excel functions: MAX, IF, ISERROR, ROW, and INDEX.
In the example shown, the formula in cell H6 is:
{=MAX(IF(...

To calculate the number of days that overlap in two date ranges, you can use basic date arithmetic, together with the the MIN and MAX functions.
In the example shown, the formula in D6 is:
=MAX(MIN(end,C6)-MAX(start,...
