An EDI (Electronic Data Interchange) translator is a software application that facilitates the exchange of electronic business documents between different computer systems. It acts as a middleware, translating data from one format to another to ensure compatibility between different systems. EDI translators can convert different types of data formats, such as EDIFACT, X12, or XML, and are commonly used in supply chain management, logistics, and healthcare industries. These translators help to streamline business processes and improve efficiency by automating the exchange of electronic data between different trading partners.
