Hi, I'm trying to do exactly what is described in this post: Tagging face names from Google Takeout json files (https://exiftool.org/forum/index.php?topic=11841.0) 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 (https://exiftool.org/exiftool_pod.html#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.
