Cell contents - Percentage match?

[JazzSP8]

Hey All

I'm after a method of comparing two cells and seeing how similar they are, preferably in a percentage format based on the words in the cell.

So;

A1 = "Apples" | B1 = "Apples" - The result would be 100%

A1 = "Apples" | B1 = "Banana" - The result would be 0%

A1 = "Apples Banana" | B1 = "Apples" - The result would be 50%

I'm thinking I might have to go the UDF route, but, thought I'd see if I'd overthought it first LOL

Thanks in advance for any help you can provide

What other scenarios might there be ?

A1 = "Apples Banana Plum" | B1 = "Apples Orange Grape"
Result = ?

Good question.

It's the number of matching words I'm after compared to the whole, using your example I'd be looking for a result of 33%

One word of three matches.

A UDF might be preferable, if only for maintainability. But if you are looking at whole words within the string, then this formula might work for you:

	A	B	C
Apples	Apples
Apples	Banana
Apples Banana	Apples
Apples Banana Plum	Apples Orange Grape
Apples Orange Grape	Apples Orange
Apples Banana Cherry Grape Tangerine	Banana Tangerine
Apples	Grapes Pear Apples
Apple	Apples
apples	Apples
