Free SQLite Query Formatter & Beautifier Online

SQLite keeps a small core but is used for surprisingly sophisticated application queries. A single script may contain PRAGMA statements, transactions, recursive CTEs, triggers, schema DDL, JSON functions, and window expressions. Identifiers can be quoted in several ways, and SQLite uses dynamic typing rather than enforcing a server-wide column type model. A formatter should therefore preserve the author’s expressions and statement order instead of assuming a larger database dialect.

This SQLite formatter handles the patterns found in migrations and embedded application databases. Recursive CTE branches are indented consistently, JSON functions and the -> and ->> operators remain attached to their paths, and GROUP_CONCAT or other aggregate calls keep their separator arguments readable. Window clauses, savepoints, and semicolon-separated statements are kept distinct so a complete migration script can be reviewed as one document.

The editor starts with a recursive category query using JSON extraction, aggregation, and a depth-aware ordering. Use this page for migration cleanup, test fixtures, local reporting queries, or SQL copied from a desktop database browser. After formatting, the diff view highlights the layout changes and the normal request path discards the query when the response is complete.

The sample also shows how ordinary relational clauses and SQLite JSON expressions can share one readable statement.

That makes it easier to check a migration before it runs on a mobile, desktop, or test database.

SQLite scripts are often checked into application repositories, where small syntax changes can affect an upgrade path. Keeping every statement and recursive branch easy to identify makes the formatter useful for code review as well as for one-off query cleanup.

The result is deliberately conservative around SQLite’s flexible syntax. It improves spacing and nesting without pretending that every expression has a server-side type or that every pragma behaves like a standard SQL clause.
