Automated inDesign File Resizing

[defaulttjzknchvi5cy]

Hi there, 
I'm wondering if anyone is aware of any adobe (or other) products that allow you to take a inDesign key visual and automatically resize/reformat across a range of templated sizes? Possibly for print vs screen too?

Adobe Spark does something similar for social posts. Adobe Sensei does it based on Experience Cloud data. But what if you need high res print ready files and you don't have AEM?

Any help/leads?

Thanks

You'd need to setup each template for what it's used for etc. 

Then you could datamerge the content. So all data is controlled via an excel sheet saved as a CSV.

So you could have all the sizes and templates in your InDesign file as one file. And then the datamerge fields on each different page. 

Background images could be controlled via master pages.

And you can prepare a CSV file for your images with a script if needed.

I'm sure other scripters/XML enthusiasts will have better ideas 🙂
