Use serialized data in meta value field

Hi
I want to save a serialized data as post meta value but since it’s inside curly brackets it is not working. How can I save this data?
For example this:
a:6:{s:5:”width”;i:800;s:6:”height”;i:600;s:4:”file”;s:19:”2021/11/image-9.jpg”;s:8:”filesize”;i:95296;}

Thanks!

Regards,
Ahti
