JSON
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate.
JSON has become the de facto standard for data exchange on the web, and it is widely used in APIs.
Character encoding
As stated by the RFC 8259, we expect strings in uploaded JSON files to be encoded in UTF-8.
If your file contains non UTF-8 characters, you might get an error when parsing your data.
