Can I edit TagsFromFile before writing

[tbmills813]

Hi, I'm trying to do exactly what is described in this post: Tagging face names from Google Takeout json files except I would like to change one of the names in the json file before writing to the jpeg file.

Is this possible with exiftool or should I use a a different tool to edit the JSON files before copying the tags with exiftool?

Thanks!

You would use the Advanced formatting feature.  You basically insert a bit of Perl code, commonly a RegEx substitution, to edit the value of the tag before it's copied.

If you detail what you want done, we can help you with it.
