Changing equation to result within attribute

Hi,

I have to change quite old reinforcement drawings with bars described using blocks and attributes. The thing is my 3rd party software for AutoCad can make some steel summary, but it cannot handle with equations within attributes. I.e. bar amount has been introduced as 30x3 instead of 90. How can I easily transform attributes from equations to the results? 

 

I've tried export of attributes to notepad, then I've changed each "x" as multiplication symbol into "*" and paste everything to excel. Then I've added "=" as prefix to each equation to get i.e. "=30*3" in appropriate cell. Then I've copied back everything to notepad and imported to dwg file (and overwrited attributes in dwg file). The thing is, that this procedure needs a lot of steps - its easy to make some simple mistakes. Do you have any idea how to solve this problem? The best would be the easiest way to solve each equation within the attribute in AutoCad (and skip a lot of exports/copying/editing etc). 

 

 

I have attached an example of the block with attributes, where the amount of bars is presented as "SZT. 30x3" and the reffered attribute is 

called "SZTUK".
