Deleting extra layers generated by data-driven graphics?

Question

I have about 1600 PSD files that I generated using data-driven graphics. They each contain one pixel layer and eleven text layers.
The number of text layers with actual content varies. My original set of data looked something like the following in Excel:
001.jpg     A     B     C
002.jpg     A     D     E     F
003.jpg     B     G
004.jpg     A     C     G     H     I     J     K
005.jpg     F     L     M
And so on. All files have content in at least two text layers, some have all eleven with content.
I discovered right away that Photoshop would not import a data set with blank fields for some text layers, there must be actual text for each text variable. So my Excel VBA script (where I combined spreadsheets to create my data set file) added a period to each otherwise empty cell.
This made my data set look like:
001.jpg     A     B     C     .     .     .     .
002.jpg     A     D     E     F     .     .     .
003.jpg     B     G     .     .     .     .     .
004.jpg     A     C     G     H     I     J     K
005.jpg     F     L     M     .     .     .     .
Photoshop was then happy, imported the data set, and created a folder full of graphics. However, I'm now left with a bunch of files that have a bunch of dots on them. I'm looking for a way (script or macro?) to delete these extra text layers.
Ideally this script could batch process a folder full of files, parsing each text layer and deleting the ones with just a period character.
I'm also fine with regenerating the files if there is a way to not create the unneeded text layers in the first place. I thought about using a visibility variable but the layers would still be there, just hidden. I'm not sure how much that helps me.
I'm a Mac guy but stuck using Windows 7 Pro at work. I have the latest version of Photoshop CC, and some experience with C-like programming languages, so I can handle simple VB or JavaScript hacking if needed.
Any ideas or suggestions or sample code? TIA for the help.

Answer 1

Well since nobody had ideas, I spent some time with the PS scripting documentation. I was also able to find a sample script linked from John Nack's blog to start with. This is actually pretty simple, although switching back and forth from VB to JS is a pain (= in VB, == in JS as an example.)
Presumably this could test for different conditions such as font, or could use a regular expression to find specific text.
main();
function main() {
    if ( app.documents.length > 0 )
    removeExtraTextLayers(app.activeDocument);
//start at index (length-1) to avoid background layer, top layer is index 0
function removeExtraTextLayers(obj){
        for( var i = obj.artLayers.length-1; 0 <= i; i--) {
        try {
        if (obj.artLayers[i].kind == LayerKind.TEXT && obj.artLayers[i].textItem.contents == ".")
            obj.artLayers[i].remove();
        catch (e) {
