What the XML formatter does

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.

Why readable XML helps

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.

Beautify and minify behavior

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.

It reformats, it does not validate

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.

Frequently asked questions

What does beautifying XML do?

It indents each element by its nesting depth and puts tags on their own lines, while keeping a single text child inline. Comments, CDATA and the XML declaration are preserved.

Is minifying XML safe?

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

Is my XML sent anywhere?

No. Formatting runs entirely in your browser, so your data never leaves your device. That makes it safe even for XML that contains sensitive values.

What is a CDATA section?

A CDATA section holds text that should not be parsed as markup, so characters like < and & can appear literally. The formatter keeps CDATA content exactly as it is.

Does it validate my XML?

No. It reformats the document for readability and does not check it against a DTD or schema, so it will lay out XML even if it is not valid.
