I've used an excel upload method and I'm tidying up the dataset using Magic ETL. On one of my columns there is a value labelled "Test". For some reason it is pulling through as two unique values when it should only be one. I have tried to use 'replace text' but whatever I replace it with it pulls through again as two unique values. I thought there could be hidden spaces in the text but I don't know how to check or remove. Any advice?
