# Talk to your data.

Load tabular data, say what you want, and watch it happen. AI [ETL](https://en.wikipedia.org/wiki/Extract,_transform,_load): no formulas, no code.

No API key? [Take a guided tour](https://www.tamedtable.com/app/?tours=1): it replays real sessions, free.

## Every common data job, in natural language

### Transform with context

The AI understands context, so it cleans, enriches, classifies, and validates — things no formula can.

### See everything

See changes as they happen. Nothing is hidden: TamedTable is [source-available](/FAQ#busl), and runs on your own API keys.

### Reuse and automate

Every change saves as steps you replay on new data, or export as a Python script. Runs in browser and CLI.

### Read many formats

Open CSV, JSONL, Parquet, and Arrow files — local, from a URL, or a bundled sample.

## How it works

### Open a file

CSV, JSONL, Parquet, or Arrow. Local or from a URL.

### Say what you want

Works in any language: English, Chinese, etc.

### Watch changes

Dislike changes? Undo anything.

### Automate

You made a recipe; replay it on new data.

## Lazy AI execution

Preview for cents, run for real when you're sure. AI steps fill the page you are looking at; the rest waits until you ask.

## Clean up

Fix messy fields the way a person would. The AI reads each row's context before deciding.

## Enrich & extract

Add what isn't there yet. The model fills the gaps and pulls structure out of free text.

## Classify

Sort rows by what they mean. The AI reads what each row is about.

## Validate

Catch the wrong-looking rows before anyone else does.

## Process language

Summarize, translate, and classify any language.

## Be exact

The everyday spreadsheet jobs are still here; deterministic and repeatable.

## Load, save & reuse

Your work is yours to keep. Load from anywhere, save the data or the recipe, undo anything.

## Trustworthy by design

### A repeatable recipe

Each request becomes a small spec you can read. Deterministic steps run in a real SQL engine, and the same recipe replays on next month's file.

### Undo anything

Every change lands in the history. Step back one change or all of them; the original file on your disk is never touched.

### Leave anytime

Export any recipe as a plain Python script and run it without TamedTable. Your data stays in open formats; there is no lock-in to defend.

### Tested & benchmarked

CI replays 606 test scenarios on every commit. In our [benchmark](https://github.com/ZSvedic/TamedTable/tree/main/benchmarks), the default model matched hand-checked labels 96.7% of the time, at $0.15 per 1,000 rows classified.
