Indesign - Rename Style Object by CSV in

Yes, I have Excel installed and I know how to use it. I specialize in EasyCatalog automation but script writing is my weak point.

Sorry if my tense seems dry, English is not my language. 🙂

Great.

No worries, your English is perfectly fine - for me at least 😉 

Instead of a script that will read new names from the CSV file and process them in a loop, bla bla bla 😉 - you can generate script in Excel - and then just run it 🙂 

In JS, to rename a style - in a group, one level deep - you would have to do something like this: 

app.activeDocument.objectStyleGroups.item("level1").objectStyles.item("old_name_1") = "new_name_1";

For 2x levels: 

app.activeDocument.objectStyleGroups.item("level1").objectStyleGroups.item("level2").objectStyles.item("old_name_1") = "new_name_1";

I hope you get how 3rd level would look like 😉 

So, in Excel, you would've to create a spreadsheet, that will use data from your CSV file - and will build lines like the above - using concatenate().

Just remember that your names need to be enclosed in " ".

I hope my explanation is clear enough 😉 

I just prefer simple solutions 😉
