When people reach for this tool

Make a single-line document readable

Feeds, sitemaps and exported configuration files are commonly delivered without any indentation.

See where the structure breaks down

Indentation exposes a mismatched or unclosed element far more clearly than a raw dump.

Diff two XML files meaningfully

Two versions of the same document only diff cleanly once both sides share the same shape.

Practical tips

Comments and CDATA sections are kept intact, so a document with long data blocks stays bulky whatever the indentation.
Check that the document declares its encoding — mixed content can look like a formatting problem when it is really a character set mismatch.

What you get

Format and minify in one place
Strings and comments kept safe

XML Formatter — FAQ

Is my data safe?

Yes. Everything runs in your browser and nothing is uploaded to any server.

Is it really free?

Every Social-X tool is free, unlimited and works offline.

What is well-formedness?

The basic XML rule set: every opening tag closed, attributes quoted, and one single root element. A document that breaks these rules cannot be parsed at all.

Does it strip comments?

No. Comments and CDATA blocks are preserved so nothing is silently lost when you reformat a document.
