Script find/change paragraph style

[patrickbcm]

Hello i'am looking for a script that find for example a paragraph style 'Header' and change that to paragraph style 'Header 2'

Can somebody help me?

Kind regards,

Patrick

If you're not aware, you can use Find/Replace using the Find Format and Change Format in InDesign itself: 

Otherwise, you'll need to specify how you're finding your paragraphs in your script. Here's one that would iterate through every paragraph in the doc and check, but it's not very efficient. 

var allPars = app.activeDocument.textFrames.everyItem().paragraphs.everyItem().getElements();
alert(allPars.length);
for (var i = 0; i < allPars.length; i++) {
   if (allPars[i].appliedParagraphStyle.name == "Header") {
      allPars[i].appliedParagraphStyle = "Header 2";
   }
}

The cript above is not working.

I have more paragraph styles. Is there also i way with find/change by list that i can change the txt file.

For example:

text {findParagraphStyle:"Header"} {appliedParagraphStyle:"Header 2"} {includeFootnotes:true, includeMasterPages:true, includeHiddenLayers:true, wholeWord:false}

Oops, made a quick fix. Try again.

Where can i find the fix?

In the original code, repasted here: 

var allPars = app.activeDocument.textFrames.everyItem().paragraphs.everyItem().getElements();
alert(allPars.length);
for (var i = 0; i < allPars.length; i++) {
   if (allPars[i].appliedParagraphStyle.name == "Header") {
      allPars[i].appliedParagraphStyle = "Header 2";
   }
}

It's still not working. The script change nothing.

One more time. Sorry, not enough coffee today: 

var allPars = app.activeDocument.textFrames.everyItem().paragraphs.everyItem().getElements();
alert(allPars.length);
for (var i = 0; i < allPars.length; i++) {
   if (allPars[i].appliedParagraphStyle.name == "Header") {
      allPars[i].appliedParagraphStyle = "Header 2";
   }
}

If you want to find and change more paragraph styles, you can add additional if statements within the loop using the same structure as above. There are other ways to, like using Find/Replace scripting or modifying Find Change By List.

Hi,

Were you aware that you can do this manually in the paragraph styles menu? When you delete a style you have the option of replacing it with another. Just make sure the new style is not based on the original style. Here is how you would do it with AppleScript:

tell application "Adobe InDesign 2020"
tell document 1

set oldStyle to paragraph style "Header"

set newStyle to paragraph style "Header2"

delete oldStyle replacing with newStyle

end tell

end tell
