About the XML Formatter
This XML formatter takes a flat or messy block of XML and rewrites it with consistent indentation so the nesting of elements is easy to follow. Paste a configuration file, a SOAP response, an RSS feed, or any other markup and the tool reorganizes the tags onto their own lines with each level pushed in by your chosen indent. The result is a tidy document you can scan, review in a diff, or paste back into an editor.
You can pick two spaces, four spaces, or a tab character for each level of depth, which lets you match the house style of whatever project the XML belongs to. The beautify mode expands the structure for reading, while the minify mode does the reverse: it removes the whitespace between tags to produce a compact single stretch of markup that is smaller to store or send over the wire.
The formatter walks the document tag by tag rather than parsing it into a strict tree, so it stays forgiving with real world files. Opening tags add a level of indent, closing tags remove one, and self closing tags and the XML declaration leave the depth alone. Text between tags is trimmed and kept on the current line so values stay attached to the element that holds them.
Everything happens in your browser using plain JavaScript. Your XML is never uploaded, logged, or sent to any server, which makes the tool safe for internal API payloads, credentials embedded in config, and other content you would not want to leave your machine. Close the tab and nothing is kept.

Frequently asked questions
What does the XML formatter do?
It reflows XML so each element sits on its own line with indentation that reflects how deeply it is nested. Beautify mode makes the document readable, and minify mode strips the whitespace between tags to make it compact.
Can I choose the indentation style?
Yes. You can format with two spaces, four spaces, or a tab character per level of depth, so the output matches the convention used by your team or project.
Does it validate my XML?
It is a formatter, not a strict validator. It does a light check and shows a calm warning if the document looks unbalanced, but it still produces a best effort formatted result so you can spot the problem.
Is my XML uploaded to a server?
No. The formatting runs entirely in your browser with JavaScript. Your XML never leaves your device, is never logged, and is discarded as soon as you close or refresh the page.
What is the difference between beautify and minify?
Beautify expands the document with line breaks and indentation for easy reading and review. Minify removes the whitespace between tags to produce the smallest possible markup for storage or transfer.
