Free Browser-Based Tools for
Data Engineers & Developers
Efneze is a growing collection of practical tools for data engineers, healthcare integration specialists, and technical teams.
Use free online utilities to quickly inspect, format, validate, and profile structured data formats like JSON, XML, CSV, HL7, CCDA, and FHIR. When workflows grow beyond simple viewing, desktop tools under Labs offer local parsing and deeper technical inspection.
Built for Real
Data Engineering Work
Many interoperability and data engineering workflows involve repetitive tasks that are more complicated than they need to be. Efneze provides practical utilities and desktop tools to simplify those workflows.
Every tool starts by solving a real problem encountered during technical work. If a solution proves useful, it is shared with the community.
