Usage Guide

  • 1. Paste raw, unformatted, or minified SQL queries into the editor.
  • 2. Select target SQL dialect and keyword casing options (UPPERCASE vs lowercase).
  • 3. Click Format to instantly produce clean, properly indented SQL queries.

Security & Privacy Guarantee

  • 1. Formatters handle layout only; they do not check table existence or SQL validity.
  • 2. Nested dialect-specific stored procedures may remain unformatted.
  • 3. Non-standard custom scalar functions are treated as standard identifiers.

Frequently Asked Questions

Q: Does the SQL formatter connect to or validate my live database?
A: No. The formatter is a pure client-side lexical parser that requires zero database connections.
Q: Why are SQL keywords automatically converted to UPPERCASE?
A: UPPERCASE keywords follow standard SQL formatting guidelines. Set Casing to 'Preserve' if preferred.
