About this tool

DevCove XML Formatter / Validator helps backend, mobile, and platform engineers clean configuration and markup files without uploading them. Use the Monaco XML editor with syntax highlighting and error line markers, prettify messy XML with consistent indentation, validate syntax before deployment, minify payloads for transport, and share reproducible examples—all in your browser.

How to use this tool

Use this tool when you edit Maven, Android, SVG, or integration config files:

  1. Choose Format to prettify pasted XML with consistent indentation before committing or deploying.
  2. Use Validate to check syntax without changing the text—invalid lines are highlighted in the editor.
  3. Load Maven, Android, SVG, or sitemap examples to see realistic structure and namespaces.
  4. Switch indent to 2 spaces, 4 spaces, or tabs to match your project style guide.
  5. Minify when you need a compact payload for APIs, logs, or transport.
  6. Apply formatted output back to the editor when you want to keep editing in place.
  7. Copy share links to send reproducible XML examples without pasting secrets into chat.

  • Examples for Maven POM, Android manifest, SVG, and sitemap files.
  • Upload, download, copy, and apply formatted output.
  • Share links for format and validate states.
  • 100% browser-local processing; XML is not uploaded.
  • Complements the JSON Formatter and YAML Formatter for mixed config pipelines.

FAQ

Does this tool preserve XML comments?

Validation keeps comments intact, but reformatting may strip or relocate comments depending on how the parser rebuilds the tree. Keep a backup if comments are legally or operationally important.

Which XML features are supported?

The tool handles common documents with elements, attributes, namespaces, and XML declarations. It is meant for config and markup files rather than huge streaming feeds or DTD-heavy legacy systems.

Can I validate Android or Maven files here?

Yes. Load the Maven or Android examples to see typical namespace and nesting patterns, then paste your own project files for format or validate runs.

Is my XML uploaded?

No. Parsing and formatting run entirely in your browser.

How does this relate to the JSON and YAML tools?

JSON, YAML, and XML often appear together in modern stacks—API configs, CI manifests, and mobile resources. DevCove keeps separate focused tools so each format gets accurate syntax handling.
