Excel公式来检查一个单元格中的逗号分隔列表中的项是否存在于另一单元格中的逗号分隔列表中？

Question

I have a spreadsheet where every row has two columns, each containing a comma separated list of words or phrases.

Column 1                        | Column 2
---------------------------------------------------------
Orange, Pear, Sugar apple, Kiwi | Orange, Sugar apple
Banana, Watermelon, Pomegranate | Strawberry, Banana

I'm trying to create a formula that checks if the items listed in Column 2 are a subset of the items listed in Column 1 and outputs true or false .

In the above example the output should be true for Row 1 and false for Row 2.

The solutions I tried using the search and find functions only work if the items in Column 2 are listed in the same sequence, ie if Column 2 is a substring of Column 1.

Answer 1

Use this array formula:

=AND(ISNUMBER(SEARCH(", " & TRIM(MID(SUBSTITUTE(B1,",",REPT(" ",99)),(ROW($XFD$1:INDEX(XFD:XFD,LEN(B1)-LEN(SUBSTITUTE(B1,",",""))+1))-1)*99+1,99)) & ",",", "&A1&",")))

Being an array formula it must be confirmed with Ctrl-Shift-Enter instead of Enter when exiting edit mode
