In reference to the attached "Example Photo" Image...
I would like to concatenate the unique data in Columns I and K into one cell (separated by line break) and remove the duplicated information in the other columns. My goal is to have the data look like rows 2 and 7 without the duplicated rows in between.
You can download Power Query or if you have Excel 2016 it is a default its name is Get & Tranform in the Data Tab.
It will open the Query Editor
In the Options:
Go to Add Column select Custom Columna.
Concatenate field Name
[Column Named Step 5][Column Name where is the data to concatenate]
Go to the new field and click in the right corner (Arrows) and select Extract Values....
#(lf)
OK.""#(lf)""
and delete the extra""
it should be"#(lf)"
click in Done.It will create a new sheet with a table with your new data.
You can append more data in the main table and it will be just a right click refresh in the Power Query Table and you will get your data.
I made this tutorial. It is in Spanish but I am using the English Excel version.
