What is splitting and merging columns?

< 1 min read

Splitting columns means breaking one column into multiple parts based on a delimiter or pattern.
In my project, “John Doe” in Full Name was split into First Name and Last Name.
We also split Address into Street, City, and ZIP code for better analysis.
Merging columns means combining two or more columns into one.
For example, First Name + Last Name → Full Name, or City + State → Location.
Power Query provides simple options to split by delimiter or merge with separator.
It helps create meaningful attributes or simplify datasets.
Both operations improve data structure for reporting and analytics.
So splitting and merging prepare data for clearer and more usable visuals.
