How to fix trailing comma errors of azure arm templates?

I have saved my arm template with yaml extension instead of json extension, because of this the vscode added trailing commas when I save the file.

Once I rename it, i am getting this error while arm template syntax check.

How to fix this, there are many lines like these and unfortunately I don't have old file to replace.

My file:
