Is there any way, by feature, scripting or XML trickery, to extract a list of the Data Merge placeholders that are actually used in an Indesign document?
InDesign clearly has this data - it uses it in the Data Merge window to tell you which pages the listed placeholders appear on. Is there any way to get the list of used placeholders as a CSV, list, text file, etc etc?
I'm looking for a way on a very complex Data Merge project to ease fixing errors and to ease paring the data sheets down to only the fields that are in use (out of hundreds).
