Importing text into PowerPoint drops all text into a single field instead of multiple slides The most detailed "how-to" that I could find https://www.ellenfinkelstein.com/pptblog/import-text-from-word-or-notepad/ tells us to 


Open a Word or Notepad document.
Type the content if you haven’t already done so, following the guildines below.
Make sure each line, whether for a slide title or bulleted text, is on its own line. There should be no blank lines, because   these come in as blank slides!
For each slide title, format the line as Heading 1 in Word or just type in Notepad.
For each line of bulleted text, format the text as Heading 2 in Word or insert a tab in Notepad
For each line of indented bulleted text, format the text as Heading 3 in Word or insert 2 tabs in Notepad
Save the file as a .docx or .txt file.


I have followed those steps:



I added  some text that starts like so: (note that the left indents are one or more tabs):


Core Stats Concepts and Procedures
Let's get warmed up: Basic Descriptive Statistics
    Define:  N === |X|
    Population Mean:  Sum(X_i)/N
    Sample Mean:  Sum(S_i)/N
        for S_i member of X
    Population Standard Deviation:  Sqrt( Sum(X_i- mean(X))^2 /N)
    Sample Standard Deviation:  Sqrt( Sum(X_i- mean(X))^2/(N-1))
Warming Up: Additional Basic Descriptive Stats
    Mode: the most common observation(s)*
        *May be more than one observation with same cardinality
    Order Statistics : Statistics based on Sorted observation values
        Min   Smallest observation
        Median   "Middle" Observation
            Simple enough if N odd
            If N even then might be taken as the average of the (N-1)/2 + (N+1)/2 observation values
        Max   Largest Observation
    Quartiles: Expands on the Order Statistics:
        The Order Statistics
            Plus
        (0th Quartile: The min value)
        1st Quartile: The (approx) 25 percentile of  observations
        2nd Quartile: Same as Median
        3rd Quartile: The (approx) 75 percentile of  observations
        (4th quartile: The max value)
        Inter-Quartile Range:  The difference between 3rd Quartile and 1st Quartile values
        ** Show example**


The result?  Everything is put into a single textbox on a single slide with centering on each line and an overly large font. 



This has been attempted about ten times with the same result.  Any pointers?

I am on Microsoft PowerPoint for Mac version 16.12 (2018)
Apparently PowerPoint requires DOS formatted lines crlf even on Mac (how lame ..) So preprocessing via unix2dos &lt;myOutline.txt&gt; did the trick.
