Recently, we hosted Allision Kennedy on the Raw Data by P3 Adaptive Podcast. During the course of the conversation, our co-host Thomas LaRock expressed his frustration at the lack of a simple method to complete what should be a simple task in Power Query. In Tom’s example, he explained he wanted to replace a given value within the column names without individually renaming all of the columns. He pointed out that this has been possible in Office for 20+ years but requires learning some M to complete in Power Query due to the fact that column headers are not considered data.
It turns out, however, that there is an answer here. Read on for that answer.
