How to simplify a cumbersome workflow?

Question

Nearly everyday I need to update 5 large .html pages, each currently around 1.5 MB. The work involved to get these pages published is cumbersome to say the least and time consuming. I'm looking for tips or suggestions on ways to achieve this more easily and in less time.
Details:
The pages in question are: http://ppbm5.com/Benchmark5.html and the http://ppbm5.com/Benchmark5-1.html thru http://ppbm5.com/Benchmark5-4.html
Step 1, Excel:
The data are processed in Excel, sorted in 5 different ways and each sorted page is exported as a .html page. Due to some bugs in Excel, each export needs to be done with the active sheet zoomed to 10% of the original size, otherwise the conditional formatting is compromised.and messed up. So, after export, reset the zoom to 100%, resort the sheet on a different test, zoom to 10%, export to .html, zoom to 100%, resort, etc.
While not very convenient, I have not found an alternative, because the conditional formatting and color coding is crucial, so using tables in DW is not an option.
Step 2, .vbs script:
A simple .vbs script is run from the desktop and that inserts in each of the created .html files the necessary code for Spry Tooltips, Lightbox and Scroll-to-Top in a very easy and reliable way. So far, so good.
Step 3, the cumbersome process:
Each of the five pages needs to have a Spry menu inserted in a specific cell of each spreadsheet. In Excel terms cell A2/A3 (merged).
The original code in each .html page to be replaced is:
<td rowspan=2 height=67 class=xl2179194 style='border-bottom:.5pt solid black;
height:50.25pt'> </td>
and needs to be replaced with this:
<td height=67 rowspan=2 bgcolor="#EEE" class=xl2179194 style='text-decoration: none; border-bottom:.5pt solid black; height:50.25pt'>
<ul id="MenuBar1" class="MenuBarVertical">
<li><a href="http://ppbm5.com/index.html">Home Page</a> </li>
<li><a href="#" class="MenuBarItemSubmenu">Sort Results by</a>
<ul>
<li><a href="http://ppbm5.com/Benchmark5.html">Overall Results</a></li>
<li><a href="http://ppbm5.com/Benchmark5-1.html">Disk I/O Results</a></li>
<li><a href="http://ppbm5.com/Benchmark5-2.html">MPEG2-DVD Results</a></li>
<li><a href="http://ppbm5.com/Benchmark5-3.html">H.264-BR Results</a></li>
<li><a href="http://ppbm5.com/Benchmark5-4.html">MPE Results</a></li>
</ul>
</li>
</ul>
</td>
Notice: The bold figures in the code above, currently 217 can vary from page to page and from day to day. This is an Excel anomaly that is unexplainable to me. One day the first page may show 199 as the first figure and the other pages may show 198, the next day the first page may show 217 on the first page and 218 on subsequent pages.
Due to some limitations of .vbs scripting and the strange Excel behavior, I have not found a method to automatically replace this code, because it is no longer static, as the rest of the script is.
Current workaround:
I know that in the .html pages, this code is somewhere in the vicinity of line 3514. So in DW I scroll down to around that line, delete the two unneeded lines and with copy/paste from a text file insert the replacement code and correct the 'class=xl2179194' manually to the correct number. This has to be repeated for each of the 5 files.
As you can understand, far from ideal.
Step 3, uploading and optimizing:
Upload the saved .html files to the site, refresh in FF, use Firebug/Pagespeed to create a compressed .html (saves around 33 KB per file), upload again, refresh and then the next tedious step starts.
Step 4, removing unused CSS code:
Refresh the page in FF, analyze with Firebug/Pagespeed and remove the unused CSS code from the page (saves around 68 K per file) by going back to DW and manually remove all the lines on unused code from bottom to top, for instance removing lines 200-198-197-195-194- 189-186-...-23-22-21-20. Then save the file again, upload and repeat this exercise for the other files.
These optimizing steps generally result in a page speed index that improves from 81 to 85, sizable enough IMO to justify the effort, but this is cumbersome, tedious and error prone. But with the way Excel works with exports of .html files I feel like I'm in a bind.
Can anyone suggest a better, more effective workflow that is less time-consuming.

Answer 1

Thank you for your attention. I know it is often suggested to export to a database or table, but the giant complexity of all the conditional formatting with legends and color grading, based on various calculations, the added and automated charts that are based on a number of calculations as well, make that approach extremly complex, not a task I look forward to.
I don't think it's any more complex that what you're currently doing on an almost daily basis
The real issue to me is letting go of the current mindset which has obviously evolved and developed this precision exercise over time.
To me, it now has the hallmarks of a Rube Goldberg invention and is obviously a burden for you to maintain.
It's often difficult to break away from, and re-think, projects that you're close to and have an intimate knowledge of.
Is the current format set in stone or can it be done a different way? I assume you have a skilled readership which is able to digest that data as presented?
All the conditional formatting on those pages is part of Excel's toolkit to try and offer some visual meaning and comprehension to the data displayed.
This can just as easily be done with queries, filters and formatting with a database approach. In addition, a database approach allows you to re-sort, analyze and present the data in countless different ways which the current rigid presentation does not allow.
Just some thoughts.
It would already simplify my current workflow, if I were able to instruct DW to delete lines in the .html code in the following sequence:
200 - 198 - 197 - 195 - 194 - 191 - 189 - 188 - 186- 185 - 183 - 181 - 180 - 179 - 176 - etc.
Notice you have to start with the highest number first and work from there to the lowest numbered line.
Do you happen to know if it is possible to enter this list of line numbers once and then instruct DW to delete these lines in the order indicated for all open documents?
Long shot: It may be possible via RegExp expressions but I'm not skilled in the use of those. However, you're probably better off doing that manually.
