Supposing there is an employee table in Excel as below screenshot shown. And now you need to randomly select one or more employees who work in New York for 3 years from the table.
This method will introduce two array formulas to randomly select cells based on criteria in Excel. Please do as follows:
Randomly select cells based on one criteria
In our example, we need to randomly select one employee who has been working for 3 years. In the cell you will return the employee name randomly, please enter the formula =INDEX(A2:A25,LARGE(IF(C2:C25=F1,ROW(C2:C25)-ROW(C2)+1),INT(RAND()*COUNTIF(C2:C25,F1)+1))), and press the Ctrl + Shift + Enter keys simultaneously.
Note: In above formula, A2:A25 is the list you will randomly select cells from, C2:C25 is the list you will match the criteria in, F1 is the criteria cell, and C2 is the first cell of the list you will match with criteria.
Randomly select cells based on two criteria
To randomly select one employee who has been working in New York for 3 years, please enter the formula =INDIRECT("A"&LARGE(IF($B$2:$B$25=$F$1,IF($C$2:$C$25=$G$1,ROW($A$2:$A$25),0),0), RANDBETWEEN(1,COUNTIFS(B2:B25,F1,C2:C25,G1)))) into the cell you will return random employee’s name, and press the Ctrl + Shift + Enter keys simultaneously.
Note: In above formula, B2:B25 is the list you will match the first criteria in, C2: C25 is the list you will match the second criteria in, F1 is the first criteria cell, G1 is the second criteria cell, and A2:A25 is the list you will randomly select cells from.
