Load multiple JSON files from folder, extract the required data fields

Hi Team, I am new to Power BI. Can somebody please help me process the steps displayed below.

1. Load multiple JSON files (same file structure) from a folder1

2. Exatract only required data points from the JSON files

3. Save the processing done to extract those fields as a macro

4. Load different folder (ex:folder2) having different set of JSON files (same file structure as the first lot)

5.Apply the macro saved to extract the data in step3

6.Report the data connected to folder2

7.Repeat step4 and step5 whenever new folder with new set of JSON files are ready on my desktop

Thanks

Pavan
