Excel：如何仅添加一个单元格中的值，跳过其他文本和字符？

Question

I have values such as below in one single cell E2 in excel. How do I skip the paranthesis, space and the text that is there in the cell and add only the values enclosed within the brackets and show the result in D2? (5) text (5) text (5) text (10) text (10) text (15) text (10) text (10) text (20) text (10) text

I've attached an image to show an idea of how it looks.

Answer 1

=SUBSTITUTE(TRIM(SUBSTITUTE(SUBSTITUTE(TRIM(SUBSTITUTE(A1,"text"," ")),"(",""),")",""))," ","")

Answer 2

另一个，

=SUMPRODUCT(--REPLACE(A1:A10, FIND(" ", A1:A10), LEN(A1:A10), TEXT(,)))

Answer 3

If given input string is well formatted, I can extract the number with excel function.

=value(MID(F1,FIND("(",F1)+1,FIND(")",F1)-FIND("(",F1)-1))

This function is composed of 3 elemental functions.

=value(MID(  F1  ,  FIND("(",F1)+1  ,  FIND(")",F1)-FIND("(",F1)-1  ))
F1: we want to extract the number from this
FIND("(",F1)+1 : where the number start from
FIND(")",F1)-FIND("(",F1)-1 : calculates the length of the number
MID:extract a string
value :deal(cast) a string as a number
