Transforming data type in Azure Data Factory

I have a "Copy" step in my Azure Data Factory pipeline which copies data from CSV file to MSSQL.

Unfortunately, all columns in CSV comes as String data type. How can I change these data types to match the data type in SQL table.

Here is how the data is available in CSV file.

I would like to change data type of WIPStateKey to Integer and ReportDt to Timestamp. I do not seem to find an option to achieve this.

Which column data type you want to change? Or what's destination table column type? – Leon Yue

Yes as you said "all columns in CSV comes as String data type".

But when using a copy active, choose the csv file as the source, we can import the schema and change the column data type.

I created a demo.csv file for test:

I copy data from my demo.csv file to my Azure SQL database. enter image description here

During file format setting, we can change the column data type: enter image description here

Hope this helps
