Does pretty-printing change the semantic meaning of my XML?

No. The formatter only adjusts whitespace and indentation. Element content, attributes, and structure are preserved exactly. XML parsers treat the output identically to the input.

What happens if my XML file is malformed?

Malformed XML files are returned without reformatting rather than producing broken output. You'll receive the original file back so nothing is silently corrupted.

Can I batch-format multiple XML config files at once?

Yes. You can upload up to 50 files per batch, with a combined size limit of 2 GB. Each file is processed independently and returned as a separate output.

Are comments preserved in the formatted output?

Comment content may be normalized as part of the formatting process. If preserving exact comment placement is critical, review the output before committing it.

Pretty-Print XML Files for Software Developers

Minified or auto-generated XML is nearly impossible to read at a glance — collapsed tags, no indentation, no structure. Deliteful's XML formatter rewrites your files with consistent indentation and line breaks so you can actually understand what you're looking at.

Developers regularly encounter dense XML payloads: API responses, build configs, Spring application context files, Maven POMs, or SOAP envelopes. When these arrive as single-line blobs, diffing changes, tracing bugs, or handing files off to teammates becomes slow and error-prone. Readable XML is a prerequisite for effective code review.

This tool applies clean indentation to any well-formed XML file and includes an XML declaration in the output. It handles batch uploads — up to 50 files or 2 GB per session — so you can reformat an entire directory of config files in one pass. Malformed XML is returned unchanged rather than silently corrupted.
