How to Use This Tool
Step 1 — paste the SQL you want to format on the left, or click "Sample" to load an example. Step 2 — pick the target dialect in the toolbar; different dialects handle keywords, functions and operators slightly differently. Step 3 — the tool formats the query live and shows the result on the right with keywords upper-cased and 2-space indentation. Step 4 — click "Minify" to collapse the SQL into a single compact line, handy for embedding in code or logs. Step 5 — copy or download the output as a
.sql file.Common Use Cases
DBAs format long queries to inspect execution plans when tracking slow SQL; developers polish ORM-generated SQL during optimisation; code reviewers normalise SQL to enforce a shared style; database export scripts are formatted before archiving; SQL extracted from log files is beautified for re-analysis.
Technical Details
Formatting is purely syntactic — it does not perform semantic validation and cannot guarantee that the SQL is valid. String literals (single-quoted content) are preserved unchanged. Keywords are upper-cased by default (configurable), while function names are kept as-is. It supports common DML/DDL such as
SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, as well as WITH CTEs. Minify mode collapses all whitespace into a single space.Privacy & Security
SQL statements are processed entirely in your browser and never uploaded, so you can safely format queries that contain sensitive business information such as table names, columns or IP addresses.
