Jasion

Jasion, likely a misspelling of "JSON" (JavaScript Object Notation), could refer to a person's name, a place name, or, most commonly, a typographical error for the aforementioned data format. If interpreted as a misspelling of JSON, it refers to a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript programming language, Standard ECMA-262 3rd Edition - December 1999. JSON is often used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page) and is also commonly used in configuration files.

Alternatively, Jasion could be a given name or a surname, although it is not a commonly recognized one in most cultures. It's also possible it exists as a place name in a specific, less-known geographical region. Without further context, it's difficult to determine its definitive meaning beyond the high probability of being a typo for JSON.
