They want me to document Nifi flows.... In a spreadsheet

Like... Just...

Abd the existing format is just awful

I know absolutely NOTHING about this.

But this would suggest you can save NiFi flows as XML.

And then XML can be consumed by spreadsheet programs like Excel or Numbers or (I think) Sheets. (And then converted to CSV or XLSX or Tab or wetf)

That'd be where I'd be leanin' anyway.
