Does anyone know of a way to assess the reading level of a document?
Export or copy the text to MS Word.
Thanks...that's the only way I've found so far as well. Was hoping there was another way.
There are a number of online solutions too. I doubt any work directly with an InDesign file.
If it was a perfect world with perfect workflows, then sure.
I'm not sure what to tell you then. By now you've learned that there's no native solution to this in InDesign and I highly doubt there will be.
