Any risk in batch editing .c3p files to update ID/Author/email/website?

I'd like to batch update/change these four fields for all 75 or so of my project files. I see it's in project.c3proj

"author": "",

"authorEmail": "",

"authorWebsite": "",

"appId": "",

Any risk in directly editing all of these? Just change the suffix to zip, edit the files and then change it back.

Thanks
