+# JSON_Parse
+
+**json_plus::JSON_Parse(json, context)**
+
+Parses a JSON string.
+
+***json***  
+The JSON string to parse. This is a `const CHAR*` string type that can be UTF8 encoded.
+
+***context***  
+Pointer to a `JSON_PARSER_CONTEXT` structure that receives the parsing info.
+
+**Return Value**  
+A `JSON_NODE` pointer that is the 1st node in the JSON node tree.
+
+**Remarks**  
+This function will return the JSON node tree built if an error is encountered, so its important to free the node tree even if parsing fails. A simple example would look like this:
+```
+JSON_PARSER_CONTEXT context;
+const CHAR* json_string = "{ \"password\":1234\" }";
+JSON_OBJECT json_file = JSON_Parse(json_string, &context);
+if (context.errorCode != JSON_ERROR_CODE::NONE) {
+	JSON_Free(json_file);
+	printf("%s\n", context.errorDescription);
+	return -1;
+}
+```
