Pretty-Print Legacy XML Exports for Data Migration Review

Legacy systems often export data in dense, unindented XML that was designed for machine consumption, not human review. Before you can map fields, validate structure, or hand off files to a development team, you need to be able to read them — and that starts with formatting.

Data migration projects require careful inspection of source system exports before any mapping or transformation work begins. When those exports are XML, the difference between a formatted and unformatted file is the difference between a 10-minute field-mapping session and an hour of scrolling through a wall of compressed tags. Teams working on SAP, Salesforce, or ERP migrations regularly encounter multi-megabyte XML exports that are effectively opaque without a formatter.

Deliteful's batch formatter handles up to 50 XML files or 2 GB per session, making it practical to reformat an entire export set at once rather than processing files one by one. Well-formed XML gets clean indentation with an XML declaration; malformed files are returned unchanged so you know immediately which exports have structural issues before migration work begins.

Frequently asked questions

Can I use this on XML exports from legacy ERP or CRM systems?
Yes. The formatter works on any well-formed XML regardless of origin. SAP IDocs, Salesforce exports, Oracle XML outputs, and similar formats are all supported as long as the XML is structurally valid.
Does formatting change any data values in the XML?
No. Only whitespace and indentation are modified. All element content, attribute values, and structure are preserved exactly as in the source file.
What if some files in my export set are malformed?
Malformed files are returned without modification. This lets you identify which exports have structural problems before beginning field mapping or transformation work.
How many files can I reformat in a single session?
Up to 50 files per batch, with a combined limit of 2 GB. Very large individual files may be returned unchanged as a safety measure rather than parsed.
