SQL Formatter — Beautify SQL for PostgreSQL, MySQL & More
Format and beautify SQL queries for PostgreSQL, MySQL, SQLite, BigQuery and standard SQL. Choose your indent, paste, and copy clean SQL — all in your browser.
🔒 Runs entirely in your browser. Your input and output are never sent to a server or stored — fully private.
About this tool
Paste a messy or one-line SQL query and this formatter lays it out cleanly, with keywords, clauses and nesting on their own lines and the indentation you prefer. It understands several dialects — standard SQL, PostgreSQL, MySQL, SQLite and BigQuery — so identifiers and functions are treated correctly. Well-formatted SQL is far easier to review, debug and drop into a pull request. Everything is processed in your browser, so even queries against a private production schema stay on your machine.
Frequently asked questions
Why does choosing a SQL dialect matter?
Each database has its own extras: PostgreSQL, MySQL, SQLite and BigQuery differ in keywords, built-in functions and how they quote identifiers — MySQL uses backticks while standard SQL and PostgreSQL use double quotes. Telling the formatter which dialect you are using helps it recognize these pieces and lay them out correctly, instead of misreading a function name or breaking a line in the wrong place.
Does formatting change what my query does?
No. Formatting only changes whitespace, line breaks, indentation and sometimes keyword capitalization. The tables, columns, conditions and logic stay exactly the same, so the query returns identical results. The formatter also does not connect to a database or run anything — it simply rewrites the text so it is easier to read, leaving you to execute it wherever you normally would.
Is my SQL sent to a server?
No. All formatting runs locally in your browser, so the query you paste is never uploaded or logged. This is important for SQL, since a query can reveal table names, column structure and business logic, and may even contain literal values from production data.
