What this SQL tool does

Paste SQL and choose Minify or Beautify. Minify removes comment-like text and compresses whitespace around common punctuation and operators. Beautify inserts line breaks around a list of common SQL keywords and adjusts spaces around punctuation.

How to use it

  1. Paste a query into the SQL input.
  2. Choose Minify or Beautify.
  3. Review the generated text, then copy or download it if it is suitable for your use.

Important limits

This tool uses regular-expression substitutions rather than a SQL parser. It does not validate syntax or understand dialect-specific grammar. Comment markers inside string literals, quoted identifiers, procedural code, or dialect-specific constructs may be treated as comments; keyword-like text inside literals can also be reformatted. As a result, output can change query meaning. Keep the original, review the result, and test it against your database before using it. There is no multi-dialect parsing guarantee.
