Excel - Mapping External Links with Flowchart

[rjamb]

I'm working on updating a file from my work predecessor that has some external links. As I opened each external link, I find that each of those files have external links and this continues for about 5 levels deep. Is there a way or program that will map all the external links back to the original data source to help conceptualize the flow of data? It would be similar to trace precedents but across multiple files.


I'm using Excel 2016.
