Recently, I’ve been working on replacing incorrect tags, so I asked Claude to help me create a script. This script runs in Chrome’s console: after pasting the code into the console and pressing Enter, an interface appears where the user can input the tag to be replaced and the new tag to use as a replacement.
After clicking “start_replacing,” the script will begin replacing tags automatically.
In this state, while in edit mode, clicking post will resulted in automatically replace the specified old tag with the new one, so there’s no need to manually select the old tag and paste the new one. However, it is still necessary to click “submit” to complete the edit, which also serves as a safeguard in case a post is clicked by mistake (i.e., when the tag should not be replaced).
I’m not sure whether a tool with similar functionality already exists. If there is one that works better, recommendations would be greatly appreciated. Thank you!
The script：
