I think GUI tools come a cropped when they try to do too much, but can work very well in limited domains. We have recently released a GUI tool to do data transformation/ETL ( https://www.easydatatransform.com https://www.easydatatransform.com ). It is aimed more at power Excel users, than programmers or data scientists. We have tried to overcome some of the issues mentioned here: * It is only intended for the limited domain of data transformation, which limits the complexity. * No need to remember any syntax/commands for the vast majority of use cases. * The transformation template is stored in a single XML file, so it can be versioned. * You can use regexp, Javascript and command line arguments to get extra power if you need it. * It is written in C++ and is fast. Obviously it can't do everything you can do with a general purpose programming language, but it hopefully do enough for many use cases and is much easier to learn.
