About this online online SQL formatter
hidevtool SQL formatter pretty-prints messy queries from ORMs, BI exports, and database clients. Paste a statement or script, pick a dialect, then format for review or minify for logging.
Keywords can be uppercased, clauses break onto readable lines, and nested subqueries indent consistently—similar to what you expect from a desktop SQL beautifier.
Online SQL formatter capabilities
Pretty-print with dialect support
Choose Standard SQL, MySQL, PostgreSQL, SQLite, T-SQL, and other common engines so identifiers, functions, and edge syntax format correctly. Format adds indentation and line breaks; invalid syntax returns an error instead of silent garbage.
Minify SQL
Minify compacts formatted SQL into fewer lines and spaces while keeping the same tokens—handy when you need a shorter snippet for chat, tickets, or log aggregation.
Common use cases
How do I format SQL online?
Paste your query, select the SQL dialect that matches your database, and click Format. The output uses indentation and uppercase keywords for easier reading.
How do I beautify a one-line SQL query?
Paste the compact query from logs or an ORM and run Format. SELECT, JOIN, WHERE, and subqueries line up on separate rows with consistent spacing.
Does the formatter support MySQL or PostgreSQL?
Yes. Use the dialect list—MySQL, MariaDB, PostgreSQL, SQLite, Transact-SQL, PL/SQL, Snowflake, and Standard SQL are available so engine-specific syntax formats more accurately.

- What is the difference between formatting and minifying SQL?
- Formatting expands the query for humans with breaks and indent. Minifying removes extra whitespace to shorten the text while leaving the same statement structure.
- Why does my SQL fail to format?
- The parser could not tokenize the text—often a missing keyword, unclosed quote, or dialect mismatch. Fix the snippet or try another dialect before formatting again.
