What XML Formatter does
Reformats XML with consistent indentation, and minifies it back when you need the compact form for transmission.
Because it parses the document to reformat it, malformed XML fails rather than producing garbage — which makes it a quick validity check as well as a formatter.
What it does
| Format | Indents nested elements consistently |
|---|---|
| Minify | Strips whitespace back out |
| Malformed input | Fails — so it doubles as a validity check |
| Attribute order | Preserved |
| CDATA | Preserved |
| Namespaces | Preserved |
| Runs | In your browser — nothing uploaded |
| Not | A schema validator — structure only |
Detailed steps
- Paste the XML.
- Format to read it, or minify to ship it.
- If it refuses, the document is not well-formed — that is the useful answer.
Worth knowing
Use it as a first-line validity check. Well-formed XML always formats; malformed XML always fails, so a refusal locates the problem faster than reading. The commonest causes are an unclosed tag, a stray ampersand that should be <code>&amp;</code>, and mismatched case in tag names.
Frequently Asked Questions
It will not format my XML.
Then it is not well-formed. Look for an unclosed or mismatched tag, a bare <code>&</code> that needs escaping as <code>&amp;</code>, or a case mismatch between an opening and closing tag — XML is case-sensitive where HTML is forgiving.
Does it validate against a schema?
No. It checks the document is structurally well-formed, which is a different and weaker thing than conforming to an XSD or DTD. Schema validation needs a validator with your schema.
Will it change my data?
No — only whitespace between elements. Attribute order, CDATA sections and namespaces are preserved. Note that whitespace inside a text node can be significant in some formats.
Is my XML uploaded?
No, it is processed in your browser — which matters, since XML pasted into a formatter is frequently an API response containing credentials or customer data.
Is XML Formatter free?
Yes. The Vootkit free plan includes 5 tool runs a day. Upgrade to Vootkit Pro for unlimited daily use, an ad-free workspace and saved workflows.
Are my files uploaded?
No. XML Formatter runs entirely in your browser — your file is processed on your own device and never sent to a server. There is nothing for us to store or delete.
Do I need to install anything?
No. XML Formatter works in any modern browser on desktop, tablet or phone. Open the page and start.
How often can I use it? Is there a daily limit?
On the free plan you get 5 tool runs a day. When you reach the limit you'll see a prompt to upgrade, and it resets the next day. Vootkit Pro removes the cap entirely for unlimited daily use.
