Add Joins When Table Columns Don't Match

If your dataset's column data doesn't match between tables, then you can transform the column's data into the format required to create joins.

Examples of transformations include changing the data type, splitting or concatenating data in the column, or enriching the column data. The list of available transformation menu options for a column depends on the type of data in that column. See Transform Reference and unresolvable-reference.html#GUID-A51D4EA6-3493-4BAC-BAE1-6C5FB64C2DF6.
