XML Formatter
Quick answer
An XML formatter pretty-prints angle-bracket documents with predictable indentation so nested elements and attributes are easy to scan. ConvertPal uses your browser’s XML parser first: if the markup is not well-formed, you get a short, human-readable error instead of silent corruption; when parsing succeeds, the tool re-serializes the tree with two-space indents and updates character counts before and after.
Engineers and integrators paste RSS feeds, SVG fragments, Android manifests, SOAP envelopes, and legacy config blobs into the left pane, click Format XML, and review readable output on the right. Sample XML loads a small catalog document so you can see the workflow instantly. Copy exports the formatted text; Clear resets both panes. Everything stays client-side—no upload step—so you can iterate on proprietary payloads from air-gapped-style workflows as long as your browser runs JavaScript.

Common use cases
- Make minified API responses readable before attaching them to tickets.
- Teach XML structure in workshops with a fast no-install playground.
- Double-check hand-edited SVG or plist-like snippets for balanced tags.
- Chain with Base64 or URL tools when transporting encoded XML strings.

Quick FAQ
What is an XML formatter?
It is a utility that rewrites XML source with consistent indentation and line breaks so you can read nested elements and attributes quickly, after confirming the document is well-formed.
Can this tool validate XML?
It performs structural validation via the browser parser—balanced tags, legal names, and so on. It does not fetch XSD or DTD files to enforce every schema rule.
What happens if my XML is broken?
Formatting stops and you see a concise parser error (often with position hints). Fix the syntax issue, then run Format XML again.
Key benefits
- Well-formedness gate with friendly errors instead of broken output.
- Responsive split view with character delta feedback.
- Sample, copy, and clear actions aligned with other ConvertPal formatters.
What this tool does
DOMParser.parseFromString runs with the application/xml MIME type so the engine enforces XML well-formedness rules rather than HTML’s error recovery. Related utilities on ConvertPal include JSON Formatter, HTML Formatter, and URL Encoder / Decoder.
If the parser injects a parsererror node or leaves a diagnostic root element, the tool surfaces that message and skips rewriting.
On success, a lightweight serializer walks the document tree—processing instructions, doctypes, comments, CDATA, elements, and text—and emits indented lines while escaping attribute values and text according to XML rules.
How to use it
- Paste XML into the input pane (declaration, single root, namespaces supported).
- Click Format XML to validate and pretty-print.
- Read any parser message if formatting fails, fix the source, and retry.
- Copy the output or use Sample XML / Clear as needed.
Why format XML?
Indented XML mirrors the hierarchy humans already imagine—children sit one level deeper than parents—so reviews and demos move faster.
Meaningful diffs in version control depend on stable line breaks; pretty-printing removes noisy one-line blobs that hide real edits.
Support and success teams can read customer exports without opening a heavyweight IDE.
Privacy model
Your XML is parsed and serialized entirely inside the browser tab; ConvertPal servers do not receive the paste for this feature.
Clipboard copy uses the same browser APIs as any local page.
More context
Pair with the JSON formatter when gateways return both JSON and XML variants of the same resource.
Use the HTML formatter for documents meant for browsers with HTML’s relaxed rules; stay on this tool when strict XML applies.
Encode URLs or Base64 next if you need to tunnel XML through query strings or binary channels.
