Data

Data connects Claude Code to your databases and CSVs and helps you explore tables, sample rows, and schema. It reads data sources, inspects column types, and lists foreign keys and indexes so you quickly understand structure before you write queries.

It writes SQL queries you can run against PostgreSQL, MySQL, SQLite, and common cloud warehouses, and adjusts syntax across dialects. It can generate JOINs, aggregations, window functions, and parameterized queries, and it explains why a query returns certain rows.

It generates charts and dashboards from query results: line, bar, scatter, histogram, and pivot tables. It maps columns to axes, sets labels and colors, and exports PNG or interactive embeds. You can iterate on visualizations without exporting CSVs or hand-editing code.

In a real workflow, you can ask for a retention curve, get the SQL, run it, tweak the chart, and save a dashboard — all inside Claude Code. That avoids switching to a separate BI tool just to explore a table, build a chart, and share a result with teammates.
