For our company, we are looking for a content management tool, where we can store content in excel for example and anytime we change the content, the content to a linked Adobe Illustrator/Indesign document shall change automatically.
Is it possible to do so with the Adobe Experience Manager or are there any other products that can be used for this?
You can store and work on excel in AEM, as it has DAM Asset management. If AEM provides much more than just working on excel. Just have a look at below link to see what features you will get along with Excel management in AEM.
