It has been very useful so far, it is easy enought to use without any additional training or support from our business partner as well. I only had one issue while testing this application - when exporting data of different types (like products) into multiple excel files with "Create Multiple Worksheets" option enabled we got all kinds of errors which made us not able to do anything further than delete those empty sheets created by Export tool.
Make sure that if needed you can still get help…
