Frequently asked questions
What is an XML formatter?
An XML formatter (also called an XML beautifier or pretty printer) takes raw, minified, or messy XML data and reformats it with proper indentation, line breaks, and syntax highlighting. This makes XML much easier to read, debug, and work with.
Is this XML formatter really free?
Yes, completely free. There are no hidden charges, no usage limits, and no premium features locked behind a paywall. Use it as much as you need, whenever you need it.
Is my XML data secure?
Absolutely. All XML processing happens entirely in your browser using JavaScript. Your data is never sent to any server, stored, or logged. This means sensitive configuration files, documents, and data stay completely private.
What kind of XML can I format?
You can format any well-formed XML including configuration files (.config, .xml), SOAP requests, SVG files, RSS feeds, sitemaps, XHTML documents, and any other XML-based markup.
Does the formatter validate my XML?
Yes. If your XML is not well-formed (missing closing tags, incorrect nesting, invalid characters), the formatter will display an error with the specific line number and description of the issue so you can fix it.
Can I customize the indentation?
Yes! You can choose between 2-space or 4-space indentation using the dropdown in the toolbar. This lets you match your team's coding style or project conventions perfectly.
What size XML documents can I format?
Our tool can handle XML data up to approximately 10MB in size. For larger files, your browser may experience performance issues since everything is processed client-side. For typical use cases like config files and API responses, performance is instantaneous.
Do I need to install anything?
No installation required. The XML formatter works entirely in your web browser. Just open the page and start formatting. No downloads, no plugins, no setup.
Can I use this on my phone?
Yes, the tool is fully responsive and works on all devices — desktops, tablets, and smartphones. The interface adapts to your screen size for comfortable use anywhere.
