If you have plain text (
.txt) or RTF files (
.rtf) if you drag drop the files into Tinderbox (testing in v8.9.2) you get a note per file. the note $Name is the source file’s title and the note’s $Text is the source file’s text.
I tested RTF with text including bold/underline/italic text. Whether things like text highlight or embedded pictures work, I’m not sure.
If you don’t want the file, how are you making the snippets. Perhaps use a tool that makes txt/rtf files instead. In this sort of scenario there is a natural tendency to try and solve issues after ingest when stepping back that it is easier to make better input materials before ingest as it is less effort in the round.
If the snippets are the outcome of an export form some other app, do check that a better export format isn’t available or if the app supports AppleScript as it may be easy to make a custom export (or even do the whole task in AppleScript).
