description	How to use circe for JSON processing in Scala. Use this skill whenever translating Python json operations to Scala or working with circe libraries.

Scala Circe JSON

When translating Python's json module to Scala, use io.circe when requested or working with Json data structures.

Parsing JSON

• Parse JSON string: io.circe.parser.parse(string) returns Either[ParsingFailure, Json].
• Extract value safely: parse(string).getOrElse(Json.Null).

Generating JSON Strings

• Compact string output: json.noSpaces.
• Pretty printed output (indented): json.spaces2.

Navigating JSON

• Objects: json.asObject returns Option[JsonObject].
• Arrays: json.asArray returns Option[Vector[Json]].
• Access object properties: jsonObject(key) or jsonObject.toMap.get(key).
• Access array elements: jsonArray.lift(index).
