A clearer way to read DuckDB

Keep the detail. See the structure.

Use this workspace to inspect analytical SQL, CTEs and relational expressions. Paste your source, choose format, and follow the resulting structure. The sample button supplies a starting point only when you request it.

Formatting helps with reading and structural review. It does not replace the language compiler, database validation or testing of application behavior.

Before you begin

What should I paste here?

Paste DuckDB source you want to study, especially analytical SQL, CTEs and relational expressions. Your input starts empty; loading a sample is optional.

Does formatting execute my code?

Formatting does not execute submitted SQL or application code. The separate Web page preview can run browser-side content in an isolated frame after you choose to open it.

How is my code handled?

The hosted site processes formatting on its server. Formatting activity stores the exact submitted source and its outcome. Direct local-file training works without activity requests. See our privacy information before submitting sensitive code.
