JSON array to multivalued processor

Anthony Pépin Updated by Anthony Pépin

This processor extracts multiple values from a field containing a JSON array and concatenates them into a multivalued field.

The multivalued property will not be set automatically in the field, so don't forget to enable it on the field's parameters, along with the same separator as in the processor.

Setting the processor

The parameter "iJSON rule to array" works exactly like in the "Extract from JSON" processor and should contain the array to concatenate (represented with the iJSON rule .item).

  • If the field contains the JSON array directly, just put item as an iJSON rule.
  • If the final element is an array, the iJSON rule must end with .item, meaning that the reached object should be treated as an array of items in the iJSON syntax.
  • If you want to keep going into the items inside the array, you can keep adding key names after the .item, but be careful to check that this path is valid for every object in the array.

To set the parameters of the JSON array to multivalued processor, follow the indications from the table below.





Name of the field that holds the JSON array


iJSON rule to array

iJSON rule to iterate in the JSON array above. An iJSON rule is built with the names of all the field from the JSON root to the data to extract, separated with a dot. The position of the array is indicated with the item keyword.



Character or string used to separate the different values found


Output field

Name of the field that will contain the extracted element



iJSON rules to extract from the following JSON array field:

"metaB" : "value1",
"int": 5,
"boolean": false
"metaB" : "value2",
"int": 6,
"boolean": true
  • item.metaBvalue1,value2
  • item.int5,6
  • item.booleanfalse,true
{ "metaA": "Joe",
"bloc" : [
"metaB" : "value1",
"int": 5,
"boolean": false,
"sub" : { "sub_sub" : "sub_value"}
"metaB" : "value2",
"int": 6,
"boolean": true,
"sub" : { "sub_sub" : "other_sub_value"}
  • bloc.item.metaBvalue1,value2
  • bloc.item.sub.sub_subsub_value,other_sub_value
