Indent XML while preserving declarations, comments and mixed content.

Privacy: runs in your browser

This tool processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Favorites store only tool names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. When a button sends your result to another tool, it waits in this tab until that tool opens it, for up to a minute, and is then deleted.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Sharing and starting over

A copied link includes what you entered and your settings, so anyone with it can see them. Leave private text out. Files and results are not included; random draws are made again.

Start over puts the tool back to its starting values and closes any open file or device. Drafts you saved stay on this device until you delete them.

Preserve text inside the tags

The formatter parses XML and reports malformed input. Conservative whitespace handling preserves mixed content, where adding spaces could change text between elements. The tree view under the result shows how the elements nest, with each element's attributes and the start of its text.

Worked example

<p>ink <b>blue</b> water</p> keeps the spaces around the bold word. An unmatched closing tag is rejected.

Before you rely on the result

No XSD validation, XPath evaluation or external document loading is provided. Document type and entity declarations are rejected. Formatting does not prove an XML document meets a business schema.
