CHOOSE selects a value from a list based on a position number. Cleaner than IF chains when mapping numbers to labels or categories.
CHOOSE returns a value from a list based on an index number you provide. CHOOSE(2,"Low","Medium","High") returns "Medium". It is cleaner than chaining IF formulas when you are mapping a number (like a rating or score) to a fixed label.
=CHOOSE(index_num, value1, [value2], ...)| Argument | Description |
|---|---|
| =CHOOSE(index_num, value1, [value2], ...) | |
| index_num required | A number from 1 to 254 that selects which value to return. |
| value1 ... required | The values to choose from. Value1 is returned when index_num is 1, value2 when 2, and so on. |
=CHOOSE(A2,"Poor","Fair","Good","Great","Excellent")A2 contains 1-5. Returns the corresponding label.
=CHOOSE(ROUNDUP(MONTH(A2)/3,0),"Q1","Q2","Q3","Q4")Converts a date into a quarter label.
=CHOOSE(WEEKDAY(A2,2),"Mon","Tue","Wed","Thu","Fri","Sat","Sun")WEEKDAY returns 1-7; CHOOSE maps to the name.
=CHOOSE(B2,"Low","Medium","High","Critical")=CHOOSE($B$1, C2, D2, E2)B1 = 1, 2 or 3 selects Base, Upside or Downside scenario.
CHOOSE, IF, IFS and SWITCH all handle conditional selection but work differently. CHOOSE maps integers to values cleanly — if your index is 1, 2, 3 or 4, CHOOSE is the tidiest solution. IFS tests conditions in order — use it when your conditions are ranges or text comparisons. SWITCH (Excel 2019+) is the most powerful: it matches a value against a list of cases, like a switch statement in programming.
A practical example: if you have a status code (1=Open, 2=Pending, 3=Closed), CHOOSE(status,"Open","Pending","Closed") is cleaner than IFS(status=1,"Open",status=2,"Pending",TRUE,"Closed").
CHOOSE also has a powerful secondary use inside VLOOKUP — you can use CHOOSE to rearrange column order, letting VLOOKUP return values from columns to the LEFT of the lookup column: =VLOOKUP(E2,CHOOSE({1,2},B2:B10,A2:A10),2,0) looks up in column B and returns from column A.
CHOOSE({1,2},B:B,A:A) creates a virtual two-column table with B as column 1 and A as column 2. Wrap this in VLOOKUP to effectively look RIGHT to LEFT — solving VLOOKUP's biggest limitation without switching to XLOOKUP.
