SQL Beautifier: Format SQL Online for 12 SQL Dialects
SQL Beautifier uses sql-formatter to turn SQL input into consistently indented, easier-to-read output. Choose among 12 supported dialects, including PostgreSQL, MySQL, T-SQL, PL/SQL, BigQuery, and Snowflake, then set indentation and keyword casing. Paste or drop a query, format it in your browser, and copy the result for reviews, documentation, or code changes.
SQL Beautifier is an online SQL Beautifier tool that uses sql-formatter to turn SQL input into readable, consistently arranged output. It supports 12 SQL dialects, including PostgreSQL, MySQL, T-SQL, PL/SQL, BigQuery, and Snowflake. Paste or drop in SQL, choose the relevant dialect, and format the result for review, documentation, or code changes.
The formatter applies indentation and other available formatting options, and it lets you choose keyword casing. These controls help make statements easier to scan without requiring you to manually rearrange the SQL. Choosing a dialect is useful when working with SQL written for different database systems, since dialects can have distinct syntax.
SQL is used to query and work with data, while formatting changes how SQL statements are laid out for people to read. A beautified query can be easier to inspect, discuss in a code review, or include in a bug report. You can also use consistent formatting to reduce whitespace differences when comparing SQL documents. SQL Beautifier formats SQL; it does not convert SQL into a different data format.
The tool runs fully in your browser. Your SQL is processed on your device and is not sent to a server, and once the page has loaded, the tool works offline. This makes it practical to format SQL without uploading query content.
SQL Beautifier is useful for developers and DevOps engineers who need to inspect, share, or tidy SQL, whether they are working with a small snippet or a larger document. Its dialect support and formatting controls help make SQL more approachable for reviews and everyday development tasks.
Step 1: Paste or drop your SQL into the input area. You can format a complete SQL document or a smaller query snippet.
Step 2: Choose the SQL dialect that matches your input. SQL Beautifier supports 12 dialects, including PostgreSQL, MySQL, T-SQL, PL/SQL, BigQuery, and Snowflake.
Step 3: Set the indentation and other available formatting options. You can also choose keyword casing to make the output fit your preferred style.
Step 4: Format the SQL and review the result. The beautified output is easier to scan and copy into a code review, bug report, or project.
Use case: Make an unreadable, machine-generated SQL file easier to review before committing it. Consistent indentation helps you focus on the query structure.
Use case: Inspect an SQL document you did not write against the specification you need to follow. Readable formatting makes the statements easier to examine.
Use case: Standardize indentation before comparing SQL changes. Consistent output can reduce whitespace noise in a diff so substantive edits stand out.
Use case: Format a query snippet before adding it to a bug report or code review. Clear layout helps other developers understand the SQL.
Use case: Check whether SQL input parses cleanly and identify the line where a parsing problem occurs. This can help you narrow down malformed input.
Use case: Adjust keyword casing and indentation to make a query easier to read in project documentation. Copy the formatted result where it is needed.
Use case: Beautify SQL written for a supported dialect before sharing it with a teammate. Selecting the matching dialect helps format the input appropriately.
