How the profiler interprets data
Missing values
Blank cells, null, and undefined are counted as missing. Zero and false remain valid values.
Column types
A column is classified from its non-missing values. Mixed columns remain categorical rather than being forced into numbers.
Auto chart
One numeric column produces a histogram, category plus numeric produces a bar chart, and two numeric columns produce a scatter plot.
