Which SQL dialects does this formatter support?

It supports Standard SQL, PostgreSQL, MySQL, SQLite, SQL Server (T-SQL), BigQuery, Snowflake, MariaDB, PL/SQL, Redshift, Spark, Hive, DB2, and DuckDB.

Can I convert all SQL keywords to uppercase automatically?

Yes, you can set the keyword casing option to UPPER, lower, or preserve the original casing.

What is the difference between standard and tabular indentation styles?

Standard style uses traditional nested spacing, while tabular styles align keywords to the left or right of a vertical column for structured readability.

Does minifying SQL remove comments and extra whitespace?

Yes, minification collapses the query into a single line and strips unnecessary spaces to optimize the query size.

Can this tool format multiple SQL statements at once?

Yes, it formats multiple statements and allows you to configure the number of blank lines between them.

SQL Query Formatter & Minifier

Beautify or minify SQL with full control over dialect (PostgreSQL, MySQL, SQLite, SQL Server/T-SQL, BigQuery, Snowflake, and more), keyword / identifier / function casing, indent style (standard, tabular-left, tabular-right), and spacing between statements. Produces a syntax-highlighted, copy-ready result with live size and statement stats.

Details

What this tool helps you do

A SQL beautifier and minifier for backend developers, BI analysts, DBAs and SQL learners:

Mode — choose Format (beautify) for readable multi-line output, or Minify (one line) to collapse a query into a single compact line.
Dialect — pick the SQL flavor (Standard SQL, PostgreSQL, MySQL, SQLite, T-SQL, BigQuery, Snowflake, …) so keywords and functions parse correctly.
Casing — independently set the case of keywords, identifiers, and function names (Preserve / UPPER / lower).
Indent — standard, tabular-left or tabular-right alignment, with configurable indent width and blank lines between statements.
Output — a dark, syntax-highlighted, copy-ready code block plus a stat strip (input/output bytes, line count, statement count, dialect).

Beautify a complex JOIN (PostgreSQL)

A crammed analytics query with LEFT JOIN, WHERE, GROUP BY, HAVING and ORDER BY, beautified with UPPER keywords and 2-space indent.

<div class="sql-wrap">…SELECT/FROM/LEFT JOIN/WHERE/GROUP BY/HAVING/ORDER BY on separate lines, highlighted…</div>

Change casing and tabular alignment

A sales query rendered with lower-case keywords, lower-case identifiers, upper-case function names and tabular-right alignment so the chosen formatting style is visibly different.

<div class="sql-wrap">…formatting profile shows tabularRight/lower/lower/upper and the code block reflects SUM + lower-case identifiers…</div>

Minify a multi-statement query to one line

Two statements collapsed into a compact single line for embedding in a string or URL.

<div class="sql-wrap">…single-line minified output, size Δ negative (shrank)…</div>
