Author Xiaoyang Last modified

Normally, you can apply formulas to combine some columns data in Excel. Now, I will talk about how to use the Power Query to merge or concatenate two or more columns. With this feature, you can merge columns to replace original ones with one merged column, or insert a new merged column alongside the columns that are merged.
