Developer & Text · SQL & XML Formatter

Format or minify SQL and XML, and check XML is well-formed

Quick answer

Open Toolfox → SQL & XML Formatter, paste SQL or XML and choose Format or Minify; the result updates as you type. XML is checked for well-formedness, with the line and column of the first problem. It runs entirely on your computer (Mac, Windows or Linux). Files are never uploaded.

Good to know

  • SQL is formatted, not validated: the formatter doesn't check that a query is correct. Minifying SQL removes comments.
  • XML is checked for well-formedness, with the line and column of the first problem. It isn't validated against a schema or DTD.
  • Elements that contain text keep their content exactly as written; whitespace between elements is treated as layout.
