What this tool handles
15 SQL dialects
Format queries for MySQL, PostgreSQL, Oracle, SQL Server, SQLite, MariaDB, BigQuery, Snowflake, Redshift, Hive, Spark, Trino, TiDB, DB2 or Standard SQL, with dialect-aware parsing.
Format or minify
Pretty-print with 2 spaces, 4 spaces or tabs for readable output, or collapse everything onto one line for logs and config files.
Keyword case conversion
Turn keywords into UPPERCASE or lowercase in one click, or preserve the original casing exactly as written.
Syntax highlighting
Keywords, strings, numbers, comments and identifiers are colour-coded so the structure of a long query is easy to scan.
Frequently asked questions
Does formatting change my query?
No. Only whitespace, line breaks and — if you choose — keyword casing change. Identifiers, string literals and the logic of the query stay exactly the same.
Which SQL dialects are supported?
Fifteen: Standard SQL, MySQL, MariaDB, PostgreSQL, SQLite, Oracle, SQL Server, BigQuery, Snowflake, Redshift, Hive, Spark, Trino, TiDB and DB2. Pick the dialect that matches your database so dialect-specific syntax is handled correctly.
Is my SQL sent to a server?
No. Formatting runs entirely in your browser. Queries pasted here often contain table structures and business logic, so nothing ever leaves your device.
Can it validate my SQL?
It catches syntax errors such as unterminated strings or unexpected tokens and reports the line and column when available. It does not check whether tables or columns exist — that requires a live database connection.
What does minify do?
Minify removes comments and collapses all whitespace onto a single line without touching string literals — handy for embedding queries in code or config files.
What does the SQL analysis check?
It reports whether your query parses under all 15 supported dialects (MySQL, PostgreSQL, Oracle, SQL Server, BigQuery and more), and scans for risky patterns such as DELETE or UPDATE without WHERE, DROP statements, SELECT * and non-portable syntax. Everything runs locally in your browser.
