Examples

Example 1

Example dataset

customer_id,email,revenue
1001,ava@example.com,89
1002,,249
1003,lee@example.com,129

Example insight

Rows: 3, columns: 3, missing email values: 1, numeric revenue column detected, no duplicate rows.

Example 2

Small dataset

A CSV or structured payload with a few rows

Quick summary

Row count, column count, detected types, and obvious issues.

Example 3

Dataset with missing values

Rows where one or more fields are blank

Completeness report

Missing counts and percentages show where review is needed.

Example 4

Dataset with numeric columns

Sales, revenue, score, duration, or other numeric fields

Numeric profile

Min, max, averages, spread, or outlier indicators where supported.

Example 5

Unknown export

A file from a system you have not inspected yet

First-pass diagnosis

The result helps decide whether to clean, validate, convert, or visualize next.

Common errors

A summary is treated as proof that the dataset is clean.
Outliers are removed automatically without checking whether they are real events.
Column types are trusted without reviewing mixed or sparse fields.
Duplicate or missing-value issues are ignored before visualization.
