The git diff --name-status main..<<branch>> gives the output in the format

R100    README.md       README_now.md
M       bootstrap/bootstrap.sh
D       configs/sample.json
A       scripts/status.py

if you look at above the command gives output which says

• The type of change in the file viz Added, Modified, Deleted, Renamed (there are also ones like file type changed etc)
• The full file path

It would be great to have this outputted as a json
