I have now taken a closer look at the application. It does not look good at all. The converted file has turned one text field into thousands. But I can't work with it like this. Maybe I should briefly describe how I normally work:
I create two brochures per year, which in principle as 2 variants always have the same structure. I only change the text and the images. At the end there are always 3-5 pages only with pictures and 4-12 pages consisting of tables, whose content I also always have to exchange. After conversion of the pdf every cell is a text field, that would drive me crazy.
So I don't know now if I can work with the application at all, or is there hope that if the IDML file can be taken over after all I have again only one text field and my tables are again reasonably editable?
Best wishes
