Issue with upload txt files to Apple Notes

1. I am facing an issue uploading txt files to Apple Notes. Is there a way to have txt filename as the note title? I have around 300 notes to upload and Notes is improperly setting the titles. Can someone share an Applescript OR Shortcuts app steps to resolve this?

2. Second issue is after uploading the txt files -> the default Notes app formating, text size and line spacing are missing on the uploaded notes. Font size has reduced. How can I apply bulk original formating and original text size to all these uploaded notes?

Thanks!
