How to Use

  1. Paste a SOAP response, exported system config, or compressed XML into the input panel, or click "Load Sample" to start with an order message example.
  2. Choose "Beautify" mode and select 2 spaces, 4 spaces, or Tab indentation.
  3. The tool parses XML locally and updates the formatted output in the right panel.
  4. If an error appears, check for closed tags, matching angle brackets, and properly escaped special characters.
  5. To reduce size, switch to "Minify" mode, then copy the XML or download it as a .xml file.

Core Features

  • XML formatting and beautifying: Turn compressed, messy, or hard-to-read XML into clearly indented structure.
  • Client-side processing: XML parsing, validation, indentation, and minification run on your device, so sensitive node values are not uploaded to EasyTools servers.
  • Live feedback: The output updates as you edit XML, with a manual "Process XML" action still available.
  • Syntax error checking: If tags are not closed, the structure is invalid, or parsing fails, the tool stops output and shows the browser parser error.
  • Custom indentation: Choose 2 spaces, 4 spaces, or Tab to match your team's config or log review style.
  • Minify and download: Switch to minify mode for compact XML, then copy the result or download it as a .xml file.

Calculation Logic

This tool uses the browser's native DOMParser to parse input as application/xml, then serializes the XML document with XMLSerializer. Beautify mode inserts line breaks and indentation around tag boundaries; minify mode removes extra whitespace between tags.

The workflow runs in browser memory, does not call a backend API, and EasyTools does not send XML text to a server. The tool does not repair broken XML; if the source has unclosed tags, illegal characters, or mismatched structure, it reports the parse error instead of generating misleading output.

FAQ

Is it safe to format XML with business data?

Yes. Parsing and formatting run locally in your browser, and XML text is not uploaded, stored, or sent to EasyTools servers.

Can I beautify XML offline?

After the page and scripts are loaded, formatting, minifying, and copying do not need backend requests. If those assets are already available in the browser, you can keep processing XML locally.

Why did my XML fail to format?

Common causes include unclosed tags, mismatched angle brackets, unescaped special characters, or multiple root nodes. The tool shows the XML parser error returned by the browser.

Does it support custom indentation?

Yes. Use the toolbar to choose 2 spaces, 4 spaces, or Tab. Minify mode ignores indentation and outputs compact XML.

Can it handle very large XML logs?

EasyTools does not set an artificial character limit. Practical performance depends on browser memory and device speed; multi-MB XML may briefly slow the page, especially with live preview.
