Hello guys,

have the following problem. My goal is to create a pivot-like table in Excel from a Power BI table. My entries in Power BI are as follows:

Date, Quarter, Product, Price

01.01.2024, Q1, Product1, 100$
01.01.2024, Q1, Product2, 400$
01.01.2024, Q1, Product3, 60$
01.01.2024, Q1, Product4, 10$
01.01.2024, Q4, Product1, 120$
01.01.2024, Q4, Product2, 150$

At the end of the flow, the result should look like this:

Date, Product1Q1, Product2Q1, Product3Q1, Product4Q1, Product1Q4, Product2Q4

01.01.2024, 100$, 400$, 60$, 10$, 120$, 150$

It is clear that one timestamps have multiple rows. I would like to compress this into a single row.

My idea was to define a variable for each column, iterate through the rows of the Power BI table, assign the respective values to the variables based on a condition, store them in an array, and then insert them into the table using "Add a row into a table." However, I am missing the logic on how to fill the array and then insert it into the table. Could someone help me with this? Thank you in advance for the help.
