Everything you need, in one platform
Not just a table viewer: a toolkit that covers most everyday data work, where every step is previewed and undoable.
Quality score & issue detection
Finds missing values, duplicate rows, inconsistent spelling, numbers/dates stored as text — and suggests one-click fixes.
Cleaning
Whitespace, placeholders, duplicates, missing data, outliers, spelling variants and type conversion — with Turkish letter rules built in.
Transformation
Filters, formula columns, group by, pivot, joins (including fuzzy), date-gap filling, unit conversion, clustering and PCA — over 50 operations.
Analysis & statistics
Regression, time-series forecasting, A/B tests, RFM, PCA, clustering, confidence intervals and more — every result comes with plain-language interpretation.
Visualization
23 chart types: combo/dual-axis, Pareto, waterfall, treemap, radar, calendar, density and more; small multiples, KPI dashboards, colour-blind safe palettes. Download as SVG/PNG.
Comparison
See added, removed and changed records between two files at cell level.
SQL queries
Run read-only SQL on your files; combine several datasets.
Export & conversion
CSV, Excel, JSON, JSONL, Markdown, HTML, SQL, Parquet, Feather, XML, Stata and LaTeX. Save repeatable work as a recipe.

Privacy and reliability are core requirements
Your data may be personal, commercial or confidential. That is why DataLab works with the least data for the shortest time.
- Your files live in an isolated workspace with a random ID that only you can access.
- You choose the retention period (1 hour – 7 days); it counts from your last activity and the data is deleted from the server automatically when it ends. You can delete everything at any time.
- File contents and file names are never written to logs.
- File validation, size limits, zip-bomb and Excel formula-injection protections are in place.
- Results are real calculations; no statistic is made up and no unverified operation is shown as successful.
