Our IT audit and internal audit teams use it and find it very useful, specially out IT audit team for ISA 315 compliance (I know still technically audit!) 

In the past I’ve used version compare frequently when reviewing contract renewals to make sure all the T&Cs are unchanged from the last legal review and export and changes to the Excel sheet.

It has been used well by tax service lines, especially for the use of data extraction here. And then FSS for accounts department.

No joke, I use it to prepare my family’s spending budget! ;)
