The underlying assumption is that all sheets have the same data table structure.
For source table different than the output table, refer to the article:
Sample data tables
Data is on four different sheets.
Pre-requisite: All data tables must be either Excel tables (CTRL+T) or Name Ranges (CTRL+F3)
Tip: Add a common keyword while defining the table or name range. For example, data_week1, data_week2, so on and so forth. It helps in filtering the right tables before combining them.
Combining all tables
Data > From Other Sources > Blank Query
It opens a blank query. In the formula bar, write the following expression:
Adding Filter Step
We can specify the type of tables we wish to combine. In this example, we want to combine all tables with names starting with data.
Filter > Text Filters > Begins With
Expand the table contents
Perform requisite data transformations:
· Change the data type
· Transform the Date into Start of Month
Close & Load (To)
We can summarize all the tables using Pivot.
Optional: Check the option when we want to analyze the data using DAX modeling in Power Pivot.
Any update automatically adds to the Pivot.
