Public Tools SQL Formatter is a free web tool for developers who need readable SQL without sending queries to a server. It formats SQL locally in the browser, supports twenty named dialects, and handles multiple semicolon-separated statements. Users can choose uppercase, lowercase, or unchanged keyword casing, along with two-space, four-space, or tab indentation. The no-account workflow suits quick formatting, privacy-sensitive query handling, and offline work after the page loads.

Its strongest fit is breadth within a focused formatter. The supported dialects include Standard SQL, PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, Oracle PL/SQL, BigQuery, Snowflake, Redshift, Spark, Hive, Trino, DuckDB, ClickHouse, Db2, N1QL, SingleStore, and TiDB. Parser diagnostics add line and column information when the input cannot be parsed, while local processing keeps the query in the browser. The product is free to use, so it works well for occasional formatting or as a lightweight utility alongside existing database tools.

The boundary is clear: this changes whitespace and keyword casing rather than acting as a full SQL quality tool. It does not validate query correctness, optimize SQL, lint database-specific issues, or provide verified autofix. There are also no stated editor extensions or CI support, which makes it less suitable for teams that need formatting enforced in a development workflow. Choose Public Tools SQL Formatter for private, browser-based formatting across many dialects; choose a broader SQL linter or development integration when diagnostics, automated fixes, or pipeline support are central requirements.
