问题 I am using apache-poi to write some data in a MS Word document. I've already spent several hours trying to figure out how to create a numbered list but I haven't achieved any results. I've gone through this, that and multiple other questions.

Q:

问题 I have a Cell object, how can I get the name of that cell? Would like a function such as: String name = myCell.getName(); In Excel I have named it in the name box, so I don't want to get 'B4', I would like to get the name such as "InterestRate".

问题 I'm working on setting up an automated processing system for a (ever growing) unstructured collection of excel documents. The collection consists of both old-school .xls files and new .xlsx files. In my Java-based solution I am already making use of the Apache POI toolkit to analyse the documents. One challenges that I have not been able to tackle yet, is how to identify links between documents so as to chart dependencies. I have not yet been able to figure out how to conveniently extract a
