Profile any Apify dataset into a per-column report: inferred type, type consistency, null rate, distinct count, uniqueness, value ranges, and top values — plus duplicate-row and empty-column detection. QA any scrape before you trust it.
Built reliability-first: every row reports what was found and what was missing — you never get a silent blank, and a run summary tells you exactly what happened.
What you get
| Field | Description |
|---|---|
column | Column |
inferredType | Inferred Type |
typeConsistency | Type Consistency |
filled | Filled |
nulls | Nulls |
nullRate | Null Rate |
distinct | Distinct |
unique | Unique |
How to use it
- Fill in the input (see the example below).
- Run it once for a snapshot, or schedule it to keep the data fresh.
- Export to CSV/JSON/Excel, or push straight to Google Sheets, Notion, Airtable, Zapier, Make, or n8n.
Input
{"items": []}
Sample output
[{"column": "example","inferredType": "example","typeConsistency": "example","filled": "example","nulls": "example","nullRate": 3.14,"distinct": "example","unique": "example"}]
Typical uses
- QA a scrape — spot empty/mistyped columns before using the data.
- Pick key fields — see which columns are unique (good dedup keys) or high-null.
- Monitor drift — schedule and watch
nullRate/typeConsistencychange over time.
Pricing
$0.50 / 1,000 results ($0.0005 per result), plus a near-zero start fee. You are never charged beyond your limit, and blocked or
failed items are reported honestly — not billed as data.
FAQ & limitations
- Public data only — no login walls, no cookies required.
- Rate limits on the source may require the proxy or a retry on very large pulls.
- Every row reports its own status, so partial results are always labeled, never faked.
- Integrations: output works with Zapier, Make, n8n, and any webhook via Apify's integrations.
- Formats: results export as JSON, CSV, Excel, or HTML from the dataset.
