NDC Diff Tool
Compare two NDC XML messages side by side. XML-aware diff highlights field-level changes, not just line-by-line differences. Normalize to ignore timestamps and UUIDs.
Diff Result
Paste two NDC XML messages and click Compare.
How this works
XML-Aware NDC Comparison
Unlike a regular text diff, this tool understands XML structure. It compares NDC messages field by field, not line by line. Enable normalization to automatically strip timestamps, UUIDs, and message IDs before comparison — useful when comparing responses from different calls or environments.
