Upload a CSV, pick your columns, and get a full data profile — every column's type, missing values, distribution, and quality flags, plus a dataset overview. Free.
Free analyses run on up to 10,000 rows. Larger files are randomly sampled to that size, so sign up to analyze your full dataset.
Profiling your columns...
Sent to . Inside: per-column type detection, missing-data map, distribution statistics, a data-quality flag list, R code, and AI insights.
Analyze another fileFor each column you map, the tool detects its type (numeric, date, categorical, constant, or identifier-like), then computes the statistics that fit that type — mean, median, spread, skew, and outlier counts for numbers; distinct-value and top-level counts for categories. It measures missingness per column, counts duplicate rows, summarizes the whole dataset, flags data-quality problems, and finds the strongest linear correlation among the numeric columns.
Use it the moment you have a new dataset and want to understand it — before regression, forecasting, clustering, or any deeper analysis.
Not a replacement for a targeted analysis — it summarizes columns one at a time and only peeks at pairwise numeric correlation. Use the correlation, regression, or group-comparison tools once you know what you're testing.
Built for: Anyone who just got a dataset and needs to understand it — analysts, operators, founders
Typical data source: Any spreadsheet or CSV with a mix of numeric, text, and date columns
Any table with a mix of column types. For example, a customer export:
Minimum 5 rows · Best with 50-100,000 rows and 3-20 columns
Standard-library analysis: the "what's in my data" report. Map the columns you want profiled and get a per-column breakdown — detected type (numeric, categorical, date, constant, or identifier), missing-value share, and the right summary statistics for each type — plus a dataset overview, a missing-data map, numeric distribution stats (spread, skew, outliers), a data-quality flag list, and a peek at your strongest numeric correlation. Works on any dataset: map 2 or more columns of any type.
Every column's type, missing share, and headline note in one table — the fastest read on what you're working with.
A bar per column showing how much data is missing, worst first — spot the columns you can't trust.
Centre, spread, skew, and outliers for each numeric column — see which are well-behaved and which are lopsided.
The problems to fix before analysis — missing data, constants, id columns, skew — each with a plain-English reason.
Plain-English interpretation of what the numbers mean, what's significant, and what to do next.
What's actually in this dataset?
Upload a CSV and map your columns. The profile detects each column's type, computes the right statistics, and flags every quality problem — so you know exactly what you're working with before running anything deeper.
See our FAQ for details on pricing, data privacy, and how the analysis works. Every report includes a Methodology section showing the statistical test, assumptions checked, and diagnostics run.
Run any analysis on your own data: validated R analyses, interactive reports, AI insights, and PDF export.
