Hi Dan,
If you have a moment check out our demo of this functionality here - https://www.modlr.co/au/demo/ad-hoc-reporting-demo
We've developed a reporting and business modelling platform which has a unique data model which allows for natural language queries of all the dimensions (equivalent to columns) of a dataset.
Here is our website for more information - https://www.modlr.co
