[Solved] How to remove null values from JSON response

by


  1. Add JSR223 PostProcessor as a child of the request which returns this JSON response

  2. Put the following code into “Script” area:

    def json = new groovy.json.JsonSlurper().parse(prev.getResponseData())

for (Iterator<Map.Entry> it = json.entrySet().iterator(); it.hasNext();) {
    Map.Entry entry = it.next();
    if (entry.getValue() == null) {
        it.remove()
    }
}

vars.put("data", new groovy.json.JsonBuilder(json).toPrettyString())

  3. JSON data without “null” elements will be available as ${data} JMeter Variable.
