    Multiply numbers from text

    Hello. I'm need to create multiple lists with different measurements in different areas. In the first cell is the text that begins with the area (E1) and continues with the measurements (product or sum). It can be best seen in the following table:

    example.png

    Columns A,B,C, D & E are merged and column F is (in this case) the product of the values from the first cell. I tried this formula i found on Google: =SUMPRODUCT(- -ISNUMBER(MID(A1,ROW($A$1:$A$200),1)+0)) , but I couldn't figure out how to the different calculations.

    To be more clear, I only want to multiply, add or subtract values such as "9,43", "5,60", "3,16" from the text in the merged cells. The numbers represent measurements and decimals may vary from 1 to 3.

    Awaiting your blessed help

    A small UDF makes it neat:

    Re: Multiply numbers from text

    Or by formula
    in B2 and copy formula down

    =LOOKUP(1E+307,0+LEFT(TRIM(SUBSTITUTE(REPLACE(A2,1,FIND("-",A2),"")," m","")),ROW(A$1:A$10000)))*LOOKUP(1E+307,0+RIGHT(TRIM(SUBSTITUTE(REPLACE(A2,1,FIND("-",A2),"")," m","")),ROW(A$1:A$10000)))

    A
    B
    2
    		 E1 - 9.43 m * 5.60 m
    52.808
    3
    		 E2 - 3.16m * 5.60 m
    17.696
    4
    		 E3 - 6.13m * 6.12 m
    37.516
    5
    		 E4 - 5.60 m * 2.97 m
    16.632

    Re: Multiply numbers from text

    Olly, I added the UDF exactly as you wrote it and I get a #VALUE error. Do I need to add anything else?

    AlKey, I also tried your formula, excel says there's an error in the formula and directs me to all the commas ","

    Re: Multiply numbers from text

    I think in your region you should use semi-colon instead of comma. Simply replace all instances of this , with this ;

    =LOOKUP(1E+307;0+LEFT(TRIM(SUBSTITUTE(REPLACE(A2;1,FIND("-";A2);"");" m";""));ROW(A$1:A$10000)))*LOOKUP(1E+307;0+RIGHT(TRIM(SUBSTITUTE(REPLACE(A2;1,FIND("-";A2);"");" m";"")),ROW(A$1:A$10000)))


    Here is also a smaller verion

    =TRIM(MID(SUBSTITUTE(MID(A2;FIND("-";A2)+2;255);"m";REPT(" ";255));1;255))*SUBSTITUTE(REPLACE(A2;1;FIND("*";A2)+1;"");"m";"")
