No black box

How this tool handles the input

The XML parser validates element structure, builds an in-memory representation, and writes it with two-space indentation. External entities are never resolved.

Before you start

What you need

One XML document without DOCTYPE or ENTITY declarations.

What you get

What the page gives back

Formatted XML ready to copy or download as .xml.

Keep in mind

Use the result responsibly

Formatting may normalize empty elements, whitespace, and attribute presentation. It does not validate an XSD or business schema.

Practical uses

Where this tool earns its place

  1. Read a compact XML API response.
  2. Clean a configuration fragment for review.
  3. Confirm basic XML well-formedness.

Verified data boundary

Source text stays on this page.

The published contract marks these tools as client-only processing. Nirmion uses the API only to confirm that this workspace is enabled in MySQL; source values and results are not sent to Flask.
