Frequently asked questions
What's the difference between the SQL Beautifier and SQL Formatter?
They share the same parser. The Beautifier is tuned for readability out of the box — uppercase keywords, a roomy 4-space indent and blank lines between statements — and is ideal for cleaning up logged or generated SQL. The Formatter exposes the casing options directly for when you want to standardise to a specific house style.
Will beautifying change what my query does?
No. Only whitespace, line breaks and keyword capitalisation change. Table and column names, string literals and the query logic stay exactly as written, and nothing is executed.
Can it handle complex joins and sub-queries?
Yes. Because it parses the SQL rather than guessing, nested sub-queries, multiple joins, CTEs and CASE expressions are indented to reflect their structure.
How do I beautify SQL online for free?
Paste your cramped or single-line query into this free online SQL beautifier, pick your dialect and indentation, and it pretty-prints clean, indented, capitalised SQL instantly. Everything runs in your browser, so there's no sign-up and nothing is uploaded.
What does a SQL beautifier do?
A SQL beautifier takes minified or machine-generated SQL — the kind ORMs and query logs produce — and reformats it into readable, indented code with uppercase keywords and blank lines between statements. It makes queries far easier to read, debug and review.
Which SQL dialects can the beautifier handle?
The beautifier is dialect-aware and supports PostgreSQL, MySQL, MariaDB, SQLite, SQL Server (T-SQL), Oracle PL/SQL, BigQuery, Snowflake, Redshift and more. Pick the closest dialect so clauses, joins and functions are laid out correctly.
Is my SQL kept private?
Yes — beautifying runs entirely in your browser. Your queries are never uploaded, logged or stored.
