Batch editing the contents of a cell

I have a huge spreadsheet that I am building to place about 10,000 products on my online shopping cart. I can create the database in excel and upload it for my entire product line but I have a question about one particular cell.

Each item has a description then in the cell next to it, there is the html of what I want the description to look like for each product when viewed online. What I want to do, since i already have all of the descriptions from my excel pricing program that I built, is to plug the descriptions into the cell containing the html.

Column U contains the descriptions. Column V contains the html code.

Example of what is in column U:
9"W x 12"D x 30"H

Example of what is in column V:
<div style="text-align: center; font-weight: bold; font-family: Garamond;"><span style="font-size: 18pt;">9"W x 12"D x 30"H Wall<br></span></div><br style="font-family: Garamond;"><span style="font-family: Garamond; font-size: 12pt;"></span>

What I want to do is replace 9"W x 12"D x 30"H Wall, which is the description in column V, with whatever is in column U but leave the rest intact.

I have used =C8&"-B2" in other parts of the sheet to copy a cell and add -B2 to it. I tried doing the same thing here, but obviously ran into problems.

Thanks in advance for any suggestions.

Below is an example in the workbook. U3 is correct, U4, U5, U6, etc are just copies of U3, but need to have the decriptions from column V inserted in the appropriate place.
dummy.xlsx

have this somewhere:

PHP Code: 

<div style="text-align: center; font-weight: bold; font-family: Garamond;"><span style="font-size: 18pt;">{replaceText}<br></span></div><br style="font-family: Garamond;"><span style="font-family: Garamond; font-size: 12pt;"></span> 


Then use (assuming the above is in V1:

PHP Code: 

=SUBSTITUTE($V$1,"{replaceText}",U3) 


However you'll also need to replace any characters with their html equivelents

Perfect! Thank you very much
