# Data Cleaner

> A table-processing tool for AI agents and people. Drop a file, get a clean table. Or call the cleaning API directly.

Data Cleaner takes a messy table and returns a clean one. It infers the type of every column, such as date, number, currency, address or free text, and rewrites each cell in a canonical form, keeping a status per cell so that nothing is changed silently. The same engine answers over a REST API, one value or one column at a time, so a script, a spreadsheet or an agent can use it without the browser.
