Create Pivot Table From Multiple Sheets
Do it for every table you got.
Next create a Pivot Table. Go to Insert -> Pivot Table. Dialog box pops out. Make sure to tick Add this data to data model box.
Pivot Table is ready. Thanks to the option ticked this is a special one. Pay attention that after clicking All you can find your created tables here.
That’s not all! You need to create Relationships here. This is a column which connects your tables. If you know data bases this is such a primary key in database.
Go to Ribbon. In the Pivot table Tools tab which appeared click Analyze -> Relationships.
Now let’s create a New Relationship. For me it is id column which I have in my both tables. The most common are: order number, product number, id, name etc.
Your Pivot Table is ready. Feel free to create one for data from Multiple Sheets.
