If you are using Sheets and need to process data in any way, you should probably look at this tool. All of the tools out there have their own spin on data cleansing. This one appears to be simple and easy to use. The add-on works as described so no issues there. It also has some custom features that are worth diving into if you are more technical. Wei from Logic Sheet is responsive if you have any issues which is hard to come by for a sheets add-on. 5 tacos.
