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 is built for the inspect-edit-copy loop developers repeat dozens of times per day. Because Utilitoo runs in the browser, you avoid context switching to desktop utilities while reviewing logs, configs, or API responses. When output feeds into production systems, validate on a staging copy first.
Common use cases
- Format and beautify XML documents - a common daily workflow on Utilitoo.
- Preparing xml formatter results to paste into pull requests, tickets, or team chat.
- Validating xml formatter data from a third-party API before wiring it into your application.
- Teaching or documenting xml formatter workflows without installing desktop software.
- Cross-checking XML Formatter output against a colleague's result during pair debugging or code review.
Tips & common mistakes
XML Formatter runs entirely in your browser on Utilitoo, so you can paste sensitive API payloads, configs, or logs without uploading them. Start with a small sample to confirm the output format, then process the full input. If results look wrong, check for trailing commas, wrong encoding, or mixed line endings - common issues when copying from terminals or log viewers. Keep XML Formatter in a pinned tab during active development - it is faster than CLI one-offs for quick transforms. Use the Related Tools section to chain utilities without returning to the homepage.
Common errors
- Unexpected output from XML Formatter - double-check input format, character encoding, and whether the source data was truncated when pasted.
- Browser limits - very large inputs may slow or freeze the tab; split the data into smaller chunks if performance degrades.
How to use
- Paste XML input.
- Click Format.
- Copy or download formatted XML.
