Warning · Table · 1 duplicate row in 1 group
Rows: 1, 2
Sensitive-looking columns: email

Issues come first, errors before warnings and observations: invalid emails, dates, and other formats, mixed types, missing and whitespace-only values, duplicate rows, repeated keys, stray spaces, and casing variants.
Every count opens the rows behind it, with hard-to-see spaces, tabs, and invisible characters made visible. Copy them in your input's format.
Each column has a profile: its detected type, how complete and distinct it is, statistics and a distribution for numbers, the top 10 values, and patterns.
Likely and possible keys and sensitive-looking columns are named. Issues that Deduplicate & Normalize can fix link to it. Nothing changes your data.
