Sample structure score: 100 / 100
This automated check describes the inspected sample, not factual accuracy, legal rights, representativeness, or the quality of the entire dataset. It is not a customer rating.
Assessed 1,000 sample records (CSV) on 2026-11-11. The sample was capped at 1,000 records.
| Check | Points | Evidence |
|---|---|---|
| Populated cells | 50 / 50 | 2000 of 2000 top-level cells contain a value. Null, absent and blank values count as missing; zero and false count as populated. |
| Consistent value types | 30 / 30 | 2000 of 2000 populated cells match their column's most common observed type. Types are inferred, not checked against real-world truth. |
| Consistent record shape | 20 / 20 | 1000 of 1000 records have the expected fields. CSV/TSV use the header width; JSON uses the union of observed keys. |
Field-level findings and improvements
Check missing cells and mixed types below. Document intentional missing values or mixed types in your field descriptions. Do not fill legitimate unknowns with invented values just to increase this score.
| Field | Missing cells | Most common type | Other populated types |
|---|---|---|---|
| bitmask_id | 0 / 1000 | number | 0 / 1000 |
| user_agent_string | 0 / 1000 | string | 0 / 1000 |
