- Choose indentation and format.
- Review the result before copying or downloading.
Format behavior and important limits
The browser XML parser checks matching tags and structure. Indentation is added only to element-only sections. Mixed text and elements, CDATA and xml:space="preserve" sections are serialized without added internal whitespace.
This does not validate an XSD or DTD. DOCTYPE and entity declarations are rejected. Quote style and empty-element spelling can change during serialization; keep source files for exact-byte workflows.
Privacy and browser support
Your input is handled in this browser tab. Selected files and entered text are not sent to Varento Tools by this tool. Some specialized libraries load only when needed. A browser with JavaScript and sufficient device memory is required. Read our local-processing explanation.

Frequently asked questions
Is this tool free without daily usage limits?
Yes. Varento Tools has no signup, accounts, usage-count caps, paywalls or watermarks. Device memory, format support and browser restrictions can still limit technically demanding files.
Will formatting change meaningful spaces?
Mixed-content sections and inherited xml:space="preserve" are kept without inserting indentation. In element-only sections, whitespace between child elements is normalized.
Is my input uploaded?
No. This utility processes input in the current browser tab. The tool code does not upload your files, tokens or text to a processing API.
What limitations should I know?
This does not validate an XSD or DTD. DOCTYPE and entity declarations are rejected. Quote style and empty-element spelling can change during serialization; keep source files for exact-byte workflows.
