I Thought I’d Never Need XML Again… Until a Client Asked for It

I Thought I’d Never Need XML Again… Until a Client Asked for It

Short summary

Enterprise systems—banking APIs, payment gateways, government platforms, and logistics software—still depend on XML despite JSON's dominance. A developer rediscovered this when a client requested XML webhooks and built a JSON-to-XML converter tool (Fixzi.ai) to handle conversions efficiently. The insight: legacy technologies remain essential infrastructure, and bridging old and new formats is a practical skill developers encounter.

  • •XML remains critical in enterprise systems (banking, payments, government, logistics)
  • •JSON-to-XML conversion is a common real-world requirement developers face
  • •Legacy infrastructure knowledge and compatibility tooling are valuable technical skills

Generated with AI, which can make mistakes.
