XML Formatter & Beautifier
Format, indent, validate, and clean XML, SVG, RSS feeds, and SOAP payloads with custom spacing.
What is the Online XML Formatter & Beautifier?
The NexTools XML Formatter & Beautifier is an online code formatting utility designed to transform compressed, unformatted, or single-line XML documents into clean, indented code. XML (Extensible Markup Language) is ubiquitous across enterprise service buses, SOAP APIs, RSS and Atom syndicated web feeds, SVG vector graphics, and Android application manifests.
When web services return XML responses or log files, they often strip extraneous whitespace and newlines to optimize payload bandwidth. Our client-side parser reconstructs tag hierarchy, nests child elements, aligns attributes, and checks document well-formedness according to W3C XML specifications without altering any text node values.
Key Capabilities of XML Beautifier
Hierarchical Tag Indentation
Customizable indentation spacing (2 spaces, 4 spaces, or tab) to maintain code legibility across enterprise style guides.
Empty Element Self-Closing
Optionally collapses redundant open-close tags like <description></description> into compact self-closing tags <description/>.
Multi-Format XML Support
Formats standard XML, SOAP XML envelopes, SVG graphics, Maven POM files, and RSS/Atom syndicated feeds.
100% Client-Side Privacy
Formatting algorithms execute in your local browser sandbox. Financial records, SOAP tokens, and internal XML feeds never leave your device.
Step-by-Step: How to Format XML Code
- Paste or Upload XML: Paste unformatted XML text into the left editor or upload an
.xmlor.svgfile. - Choose Formatting Preferences: Select indent size and toggle comment stripping or empty tag collapsing.
- Click "Format XML": The editor immediately parses and indents all tags and attributes.
- Copy or Download: Click "Copy XML" to copy to clipboard or "Download .xml" to save the formatted file locally.
Frequently Asked Questions (FAQ)
What is a well-formed XML document?
A well-formed XML document strictly complies with XML syntax rules: it must have a single root element, all open tags must have corresponding closing tags, elements must be properly nested without overlapping, and attribute values must be enclosed in quotes.
Does beautifying XML alter data content?
No. Beautification only adjusts inter-tag whitespace and indentation. Text contents inside leaf tags (e.g. <title>Hello World</title>) and CDATA blocks (<![CDATA[...]]>) are strictly preserved.
Can this tool format SVG files?
Yes. Scalable Vector Graphics (SVG) is an XML-based vector image format. You can paste any SVG markup into this tool to cleanly indent paths, groups, defs, and style tags.
Can I minify XML back to a single line?
Yes. Click the "Minify XML" button to strip redundant spaces and line breaks between tags to produce a compact single-line payload for production deployment.
