Yep, that's becoming mainstream. UNECE is currently working on a JSON schema for EDIFACT, due next year, as far as I'm aware.
The EDI standard was made independent from the transport (AS2, SFTP, etc.), so files can be transferred in any reliable/secure way, even web API/HTTP.
With this UNECE initiative, it begins to separate the syntax from the specification, e.g., to be able to transport an invoice as both a text file in EDIFACT syntax, and a JSON file in a matching hierarchy/structure.
