How can I write exif data from a json-file into a jpg-image?

Question

I've created backups of exif information with

exiftool -j -w json picture.jpg 

How can I now restore the exif information to the image file from the json-file?

Thanks

Ok found it. Might be interesting for others so I post it:

exiftool -json=picture.json picture.jpg

This writes the exif data from picture.json to picture.jpg
