When to use XML Formatter

Your CI pipeline is rejecting a sitemap.xml with a parse error at byte 8432, and the file is a single line of concatenated tags with no indentation. Paste it here and the browser's DOMParser reformats it into a nested, indented tree and flags the exact unclosed tag or bad attribute that's causing the failure. Also useful when you pull a SOAP response from Wireshark or a log file, or when a vendor exports config data as a single-line XML blob that's impossible to diff. Nothing leaves your machine — the DOMParser runs in your tab, so internal SOAP credentials and private API payloads stay off any outside server. Fix the structure, copy it back.

  • Debug a sitemap.xml rejected by Google Search Console
  • Read a SOAP response from a legacy payment gateway
  • Inspect an RSS feed before parsing it in your script

About this tool

Minified or malformed XML is painful to read — one long line with no indentation and a parse error somewhere in it. Paste your XML and get it formatted with consistent indentation and syntax highlighting; errors are flagged so you can find the unclosed tag or bad attribute without squinting at raw text. Useful for inspecting SOAP responses, debugging sitemap.xml files, reading RSS feeds, or reviewing config exports from tools that serialize to XML. Runs in your browser — no data leaves your machine, so internal API responses and proprietary config formats stay private. Format, inspect, copy.

Frequently asked

Is this formatter private? Do you upload my XML?
No. Formatting runs on your computer — your XML never leaves your device and the tool works offline.
What does an XML formatter do?
It takes unformatted or minified XML and adds proper indentation and line breaks, making it easy to read and understand the document structure.
Can this tool validate XML?
Yes — if your XML has syntax errors such as unclosed tags or mismatched elements, the formatter will display the error so you can fix it.
Is my data safe?
All formatting happens on your computer using the built-in DOMParser. Your XML is never sent to any server.
