Since generated html-files generally have a repeating structure, this might need some programming after some manual preparation.
Tools that might be used, for example, are macro's in MS Word or awk in Unix.
But the exact format needed might depend on the specific app you want to import it with.

Hi,
I lost some of my call history so I ran Dr.Fone to extract as much as possible and I extracted a lot. However, it made the file into an HTML file and I don't know how to make this file into a format the apps can use to import the call history.
I've considered transforming it to an XML file but haven't found reliable converters. Any help is appreciated.
