Yes as Mark Kromer mentioned, you can copy JSON data to the Azure SQL table using the dataflow activity.

Here are the steps to copy JSON to Azure SQL using dataflow:

1. Create a JSON dataset and connect it to the source.

2. Source data preview:

3. Connect the source output to flatten transformation and under Unroll by and Unroll root, select " rows " array.

4. You can remove the columns which not required to pass to the sink.

5. Data preview after it is flattened.

6. Add sink transformation and connect to Azure SQL table dataset.

7. In mapping , add or remove mapping as per the output columns.

8. Output data of sink.

9. Add the dataflow activity to the pipeline and execute it.

10. Data loaded to Azure SQL table .
