# Spreadsheets you can question

> Drop a CSV or JSON into the chat and it becomes a queryable table. Ask in plain language; get a number, a table or a chart.

The bank export, the sales sheet, the workout log — the data you actually have lives in files nobody opens twice. Give the file to the assistant and it becomes a table you can ask about for years.

## Ask, don't filter

Questions become queries behind the scenes. The answer comes back as the right shape: a single number, a small table, or a chart when you ask for one.

## How it works

There is no “create table” step. Posting data to a table name creates it, infers the columns and types, and stores the rows in a form built for fast analytics. Later posts to the same name append and extend the columns. Queries run on an analytical engine; every project's tables are kept apart from every other project's, so a query can never see another project's data. Changes the assistant makes to rows are previewed first and can be undone.

## In the app

The Data tab lists your tables with columns and row counts, lets you add rows and preview them. Queries run from the chat; a result can be opened in full or fed into an automation.

## Saved charts <Soon />

A chart the assistant drew in reply to a question, pinned to the project as a card you can come back to.
