Break links to style

In fact there is unfortunately no command like "...breakLinkToStyle(...)" or so. What you need to do is the following in order to break the link from ... :
table to table style:

table.appliedTableStyle = app.activeDocument.tablesStyles[0];
table.clearTableStyleOverrides();

cell to cell style: analogous, replacing "table" by "cell";

object to object style: analogous, replacing "table" by "object";

paragraph from paragraph style:

text..applyParagraphStyle(app.activeDocument.paragraphStyles[0], false);

character from character style:  analoguous, replacing "Paragraph" by "Character".

Not kind of straighforward, but anyway, it works.

Hi @Veronica22551996i6fw , I don’t think there is a break link to style command in the scripting API, but you can select all the paragraphs and invoke the menu item via scripting, so you can try this:

var doc = app.activeDocument
var bls =  app.menuActions.itemByID(8500)

for(var i=0; i < doc.stories.length; i++){  
    var s = doc.stories.item(i);  
    for(var j=0; j < s.paragraphs.length; j++){  
        var p=s.paragraphs[j]; 
        p.select()
        if(bls.enabled){  
            bls.invoke();  
        }; 
    }  
} 

If the text is threaded, of course, you can Select All and choose Break Links from the Para Styles menu. If the frames are not threaded, I think you'll have to select each frame. You can select multiple text frames and Break Links on all of them at once, provided they are not threaded to another page/spread. 

The only other thing I can think of is to search out whether there's a script to automate further.
