What SQL dialects are supported?

Standard SQL including SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and more.

Does it preserve my data?

Yes, string literals and comments are preserved during formatting.

Does minifying change how my query runs?

No. Minifying only removes whitespace and line breaks; the query executes identically.

Is my SQL sent to a server?

No. Formatting runs entirely in your browser, so your queries never leave your device.

SQL Formatter | HandyTools Hub

SQL Formatter turns cramped, single-line queries into clean, readable statements — or compresses verbose SQL down to a compact form for logs and production. Paste your query, choose your style, and get properly indented SQL in one click. It is built for developers, data analysts, and DBAs who live in query editors all day.

How to Use

Paste SQL: Drop your query into the input box — even a 500-line mess is fine.
Format or Minify: Click Format to beautify, or Minify to strip whitespace.
Set options: Pick UPPERCASE or lowercase keywords and your preferred indent size.
Copy: Copy the result straight back into your editor, ticket, or chat message.

Features

Formats SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER and more
Minify mode for compact, production-ready SQL
Customizable keyword case and indentation width
Preserves string literals and comments exactly as written
Handles MySQL, PostgreSQL, and SQLite dialect conventions

Why Format SQL?

Readable SQL is not a luxury — it is how teams catch bugs. A WHERE clause buried at the end of a one-line query is easy to miss during review; the same clause on its own indented line jumps out immediately. Consistent formatting also makes diffs meaningful in version control: when everyone uses the same keyword case and indentation, a pull request shows the actual logic change instead of a wall of cosmetic noise.

Minified SQL has its place too — embedding queries in application logs, URL parameters, or anywhere every byte counts. The one thing to watch out for is formatting inside string literals: a naive formatter can corrupt quoted text and turn 'New York' into something that breaks your query. That is why this tool leaves literals and comments untouched, no matter which mode you use.
