SQL Formatter

Paste or load SQL, click Format for line breaks and indentation (4 spaces by default, switch to 2), or Minify to strip extra whitespace. Keyword casing is separate. The formatter uses the open-source sql-formatter library in your browser (PostgreSQL grammar by default), producing layouts similar to common tutorial examples. Nothing is uploaded.

Input SQL

Output

0 Formatted (4 spaces)

Step 1

Paste SQL on the left or use “Load file” for a .sql or .txt file.

Step 2

Click Format for line breaks and indentation, use 2 or 4 beside it for spaces per level, or Minify for the smallest output. Keyword casing uses the three buttons on the right.

Step 3

Review the right pane, then copy or download the output.

When should I use this tool?

Whenever you need readable SQL from logs, ORM output, or a database client—for reviews, docs, or pull requests—without sending the text to a server.

Does formatting change query results?

It should not change semantics: only whitespace, line breaks, and keyword appearance. Always verify on a non-production database before relying on it.

Which SQL dialects are supported?

Format uses sql-formatter with PostgreSQL as the primary dialect (it falls back to generic SQL if parsing fails). WITH clauses, window functions, CASE expressions, and CREATE TABLE layouts will look close to common tutorial examples; exotic vendor extensions may still need manual tweaks.

Is my SQL sent to your servers?

No. Formatting runs entirely in your browser; we do not store your input after you leave or refresh the page.

Why are some parts not wrapped to new lines?

The engine breaks major clauses, column lists, and parenthesized blocks. If the source SQL is incomplete or uses unusual extensions, the layout may look off—try keyword “keep as typed” mode or paste smaller fragments.
