  • JSON FormatterFormat query results.
  • Text Diff CheckerCompare query versions.
  • Code MinifierMinify frontend code.

SQL Formatter indents SELECT, JOIN, INSERT, and CTE statements so code reviews and documentation are easier to read.

Minify mode collapses whitespace when you need a compact single-line query for logs or embedded scripts.

Runs locally — avoid pasting production credentials even when processing stays on your device.

Common uses for SQL Formatter

Typical tasks this tool is built for.

  • Format long SQL queries for debugging and review.
  • Make joins, filters, and conditions easier to read.
  • Minify SQL into a compact single-line output.
  • Standardize SQL style for internal documentation or team sharing.

How to use SQL Formatter

  1. Step 1. Paste your SQL into the input area (SELECT, INSERT, JOINs, CTEs, etc.).
  2. Step 2. Choose format or minify depending on whether you need readability or compact output.
  3. Step 3. Scan the output for broken strings or comments — exotic dialect features may not format perfectly.
  4. Step 4. Copy the formatted SQL into your editor, migration file, or ticket.

Why use this tool?

  • Pretty-print messy SQL with consistent indentation for reviews and documentation.
  • Minify mode compacts queries for logs or embedded scripts when you need a single line.
  • Runs locally — queries are not sent to a formatting server.

Privacy and formats

SQL formatting and minify run locally in your browser. Queries are not sent to a server.

Best results with SQL Formatter

Practical tips before you download or share the output.

This formatter improves readability for common SQL patterns, but it is not a full SQL parser. Very advanced procedural SQL may need custom handling.

Common problems this tool helps with

Situations where this workflow saves time.

Stored procedures with nested blocks — formatting may be imperfect; split and format sections.
Very long generated SQL — browser tab may slow down; format chunks instead.
Dialect-specific syntax — formatter targets common SQL, not every vendor extension.
Secrets in queries — even local tools should avoid pasting production passwords on shared machines.

Frequently asked questions

Is my SQL sent to a server?

No. Formatting and minify run locally in your browser.

Does this validate SQL syntax?

It improves readability. It does not execute or fully parse every database dialect — always test on your database.

Can I format minified SQL from logs?

Yes. Paste the one-line query and run format mode to expand indentation.

Will comments be preserved?

Common -- and block comments usually survive, but always verify before running against production data.
