@LMc was very helpful with his answer here.
The bulk of the info I needed is present with using the file.info function.
For exporting these file properties. But now I am being asking to add in the original author's name and the person to last modify the file. Essentially, two more columns with this information. A quick google search appears that file.info will not provide these details.
Is there a workaround to to make these additions to this spreadsheet?
