XML Formatter
Format and beautify XML documents.
XML documents from legacy APIs, SOAP services, Maven POM files, and enterprise configs are painful to read when compressed onto a single line. Utilitoo's XML Formatter parses your input, validates the structure, and outputs consistently indented XML you can review, diff, or paste back into your project.
Integration engineers inspecting SOAP responses, Java developers reviewing pom.xml snippets, and DevOps teams tidying XML configs copied from logs all need fast pretty-printing without IDE plugins or command-line xmllint installs.
Paste XML, click Format, and copy or download the beautified result. Invalid XML shows a clear parse error instead of broken output. Pair with XML to JSON when you need structured data, JSON to XML for round-trip testing, or Diff Checker when comparing two XML versions.
Formatting runs entirely in your browser on Utilitoo. Your XML payloads, internal configs, and API responses are never uploaded to any server. Free, fast, and privacy-first for developers working with XML daily.
XML Formatter focuses on structured text people edit by hand: Format and beautify XML documents. Indentation and delimiters matter - preview changes on a copy before rewriting a large manifest.
Common use cases
- Turning messy xml formatter data into something readable during a live debugging session.
- Sanity-checking exports from databases, queues, or SaaS admin panels with XML Formatter.
- Building fixtures and examples for docs or tests from real xml formatter samples.
- Avoiding a full IDE or CLI install when you only need a one-off xml formatter transform.
- Reproducing a reported bug by pasting the exact xml formatter payload the user shared.
Tips & common mistakes
Use XML Formatter when you need a fast browser-side check: Format and beautify XML documents. Prefer plain-text pastes over rich HTML from email clients. For production-bound transforms, validate on a staging copy first. Large inputs can slow a tab - split multi-megabyte blobs when the UI feels sluggish.
Common errors
- Unexpected output from XML Formatter - double-check input format, encoding, and whether the paste was truncated.
- Browser limits - very large inputs may slow the tab; split into smaller chunks if performance drops.
How to use
- Paste XML input.
- Click Format.
- Copy or download formatted XML.
