CSV Data Profiler

Point it at any CSV — get an instant, structured profile of every column: data types, nulls, uniqueness, numeric stats, top values, and data-quality warnings.

Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.

What you get

Per-column type inference — integer, float, boolean, date, or string.
Completeness — null percentage and unique count for every column.
Numeric stats — min, max, mean, median, and standard deviation.
Categorical stats — min/max string length plus the top 5 most frequent values.
Data-quality warnings — high-null columns, mixed types, constant columns, and likely identifiers.
Works from a file URL or pasted raw CSV, with a row-sampling cap for big files.

Input

{
  "url": "https://raw.githubusercontent.com/datasciencedojo/datasets/master/titanic.csv",
  "maxRows": 5000
}

Or paste raw CSV directly:

{
  "csv": "name,age,active\nAlice,30,true\nBob,,false"
}

Output

{
  "source": "https://.../titanic.csv",
  "rowCount": 891,
  "columnCount": 12,
  "columns": [
    {
      "name": "Age",
      "type": "float",
      "nullPct": 19.87,
      "unique": 88,
      "stats": { "min": 0.42, "max": 80, "mean": 29.699, "median": 28, "stddev": 14.516 },
      "topValues": [{ "value": "24", "count": 30 }]
    },
    {
      "name": "Sex",
      "type": "string",
      "nullPct": 0,
      "unique": 2,
      "stats": { "minLength": 4, "maxLength": 6 },
      "topValues": [{ "value": "male", "count": 577 }, { "value": "female", "count": 314 }]
    }
  ],
  "warnings": ["Column \"Age\" is 19.87% null."]
}
