XMLフォーマッター

This is an XML formatter that beautifies a document with proper, depth-based indentation, or minifies it to a single line. It preserves comments, CDATA sections, processing instructions and the XML declaration.

Formatting runs entirely in your browser, so your data never leaves your device, which makes it safe even for XML that contains sensitive values.

XML is verbose and deeply nested. Indenting each element by its depth and putting tags on their own lines turns a wall of angle brackets into a structure you can actually follow.

It is useful across the many places XML still lives: SOAP responses, RSS feeds, build and config files, and document formats, where a quick reformat makes debugging far easier.

Beautifying keeps a single text child inline with its tags, so simple values stay compact, while the declaration, comments and CDATA are kept exactly as they were rather than being reflowed or dropped.

Minifying removes comments and the whitespace used only for indentation between tags. Text content and CDATA are kept exactly, so it is safe unless your document relies on significant whitespace in mixed content.

The tool reformats for readability and does not validate against a schema. Clean layout does not mean the document matches any DTD or XSD you expect.
