We prototyped a new taxonomy for files by using pivot tables in Excel. There are several categories in the taxonomy, and some frequently have multiple values for the same file, while others remain the same. To make the pivot tables work, we have to have a separate row for each value. However, to upload the data into the real tool, the multiple values have to be in one cell for each file, separated by a semicolon with no spaces.
We anticipate a few revisions, and so it would be useful to have macros that can go in both directions: one to concatenate the rows and delete duplicates, and the other to split the rows up to make one value per row. There are about 5000 files in the data set.
I have found a number of scripts online that do almost what I need, but my VBA skills aren't up to finishing the job. Thanks in advance for your help. I've attached a mini sample file that contains the common variations. There's one worksheet showing the starting point (split rows), and a second one showing the desired end point (concatenated rows).
