XML Formatter Online - Step by Step

Open XML Formatter Online, paste your raw XML, click the button, and copy the indented result. No install, no account - the whole process takes under 10 seconds.

Step 1 - Open the tool

Go to developer-tools/xml-formatter.html. The tool loads instantly in the browser - nothing is installed or downloaded.

Step 2 - Paste your XML

Click inside the left text area and paste your XML. This can be a minified API response, a config file, an SVG block, or any well-formed XML string. The input area accepts any length.

Step 3 - Click Format and review

Click the XML Formatter Online button. The indented XML appears in the right pane immediately - each nested element is indented two spaces, and empty elements appear as self-closing tags like <item />. If the input is not valid XML, the right pane shows the parse error.

Step 4 - Copy the output

Click Copy Output to copy the formatted XML to your clipboard. Paste it wherever you need it - a code editor, a commit message, a documentation page. No data leaves your browser at any point.

Why trust these tools

  • Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
  • No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
  • Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
  • Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
  • Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
