First, we'll export csv file to Google Sheets. Click "Competitors" at the top
In Competitor List, select "Luxury"
Select "Cross Channel" on the left. Then you might have to wait for a moment while it loads metrics
After that click Export and select "Export to Google Sheets - Metrics"
Then, we will upload exported file to a new data source in Google Data Studio
Navigate to "Data Sources" on Data Studio home page
Click plus button at the bottom right corner to create a new data source
Find "Google Sheets" and click "Select"
Select the file that you just exported
...And click "Connect"
Then we'll have to adjust field types to correct ones
For each field that should be numeric, change its type to Numeric -> Number
For Active Audience you can select "Percent", but it's actually not necessary
Then we will copy a report template and select the newly created data source for it
Move back to the home page and open the report
Enter Edit mode
Click "File", then "Make a copy"
As a New Data Source, select the data source that you just created
Click "Create Report"
And that's it, the report is ready!
