Percentage from cell containing numbers and text

[AWatson]

Hi,

Is it possible to calculate a percentage from a cell that contains two numbers and text within the same cell? And is this possible without separating the numbers into separate cells?

E.g. If A1 contained the value "4 (19)", is it possible to create a formula to use the cell contents to calculate a percentage of 21% i.e. 4 of 19?

Similarly, if B1 contained the value "10 (20)", to calculate this as 50% (formula result in B2)?

The second number will always be in brackets.

Many thanks,

Try this.

Excel Workbook
	A	B
1	4 (19)	21.05%
2	10 (20)	50.00%
3
Percentage

=LEFT(A1,FIND(" ",A1))/-MID(A1,FIND("(",A1),FIND(")",A1))

The first part takes the number left of the space and the next part looks at the number in the parenthesis. The second part required a minus sign because excel reads the number as a negative.

You answered before I could finish ! Thanks for the different perspective. I am constantly amazed at all the different ways Excel can handle things.

It may not be possible with the OP's data but the blue part would cause an error with your formula if there is a negative in the parentheses. For example try:
4 (-19)

The formula in the first reply works perfectly. Thanks very much for your help.

Is there a way to deal with errors e.g. if the both numeric values in A1 are zeros i.e. "0 (0)" and the result is #DIV/0! or if the cell is blank with data yet to be entered and the result is #VALUE!

try this:

=IF(OR(A1="",COUNTIF(A1,"*(0)*")),"",LEFT(A1,FIND(" ",A1)-1)/SUBSTITUTE(REPLACE(A1,1,FIND("(",A1),""),")",""))

That's brilliant - thanks again for your help. I would never have managed that on my own!!

Very good point...I did not consider the effects of a negative number. Thanks for pointing that out.
