Can I use this to inspect the schema of an unfamiliar XML data feed?

Yes. Pretty-printing is one of the fastest ways to understand an unfamiliar XML structure — once indented, element hierarchies, nesting depth, and repeated nodes are immediately visible.

Does formatting affect how downstream parsers read the file?

No. Added whitespace is insignificant to XML parsers. The formatted file is semantically identical to the original.

What is the file size limit for XML formatting?

Each individual XML file can be up to 50 MB. Per batch, you can process up to 50 files or 2 GB total, whichever is reached first. Very large files may be returned unchanged for safety.

What happens to XML files that fail to parse?

Malformed XML is returned without modification. This prevents silent corruption and lets you identify which files in a batch have structural issues.

Readable XML Formatting for Data Engineers and ETL Workflows

Raw XML exports from databases, legacy systems, and third-party data feeds arrive compressed and unreadable — making schema inspection, pipeline debugging, and handoffs needlessly painful. Deliteful reformats those files with clean structure so you can get back to building.

Data engineers spend significant time deciphering XML: inspecting namespace declarations, tracing element hierarchies in complex feeds, or verifying that a transformation produced the right output structure. Without readable indentation, this work is slow and mistake-prone — especially on files with deep nesting or many repeated elements.

Deliteful handles batch processing natively, so you can reformat an entire set of XML exports from a single pipeline run in one upload. Files up to 50 MB are supported individually, with up to 50 files or 2 GB per batch. Well-formed XML gets clean indentation; malformed files are returned as-is so your pipeline doesn't silently ingest corrupted data.
