Count by group
The Count by group step counts the number of rows that exist for each unique value in one or more columns. This step is similar to the COUNTIF function in Excel.
Input/output
Our input data is a list of product variants.
We want to know how many product variants we have available at different price points. After connecting the data to this step and setting it up, it gives us the output data of the unique variants amount per unique sale price.
Default settings
By default, this step will count every row as unique and display a "Count" column with the same value as the number of rows in your input table.
Custom settings
To customize these default settings, you'll first select a column or multiple columns you'd like to count unique values for. Then, you'll provide a name for that new column that will display the count of unique values.
In the example above, we wanted to count unique variants per unique sale price, so we selected Sale Price from the dropdown and named the new column "Variant Count".
We can add multiple columns if we want to count unique values for the combinations of those column values.
To build on the example above, if we want to count unique variants per sale price and product name, we can select both of those columns from the dropdown to see these updated results. The screenshot below shows us that I have 3 variants of "Tees" priced at $25 available in our store.
