To find the longest string (name, word, etc.) in a column, you can use an array formula based on INDEX and MATCH, together with LEN and MAX. In the example shown, the formula in F6 is:
{=INDEX(names,MATCH(MAX(LEN(...

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 total number of hours between a start and end time that overlap a period of interest with a given start and end time, you can use a formula based on the IF, MAX, and MIN functions. In the example...

Note: these is an experimental formula that uses a hard coded array constant, set down here for reference and comment. Casually tested only, so take care if you use or adapt.
Sometimes you encounter data that mixes...

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 count consecutive monthly orders, you can use an array formula based on the FREQUENCY function, with help from COLUMN and MAX.
In the example shown, the formula in I5 is:
{=MAX(FREQUENCY(IF(C5:H5>0,COLUMN(C5:H5...

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 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 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 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 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 get the position of the maximum value in a range (i.e. a list, table, or row), you can use the MAX function together with the MATCH function.
In the example shown, the formula in I5 is:
=MATCH(MAX(C3:C11),C3:C11,0...

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 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]/[@...
