Custom JavaScript code

You can use custom JavaScript code in the account to modify Jira issues field values during import. The JavaScript code will modify the issue JSON object before importing issues into account. 

Custom Javascript code can not be used to create new custom fields for It updates existing fields only.

How to add and validate custom JavaScript code

Custom JavaScript code should be added to each account where you would like to make data modifications. Open Jira import options of the account, in tab Additional options click Add custom JavaScript code to show the code editor.

Then add some Javascript code in the code editor [1]. You can test the code for one sample issue key in the validation area [2]  and see results in the results pane [3] [4].

JavaScript code should be ES5 compliant, ES6 syntax is not supported.

You can use issue variable to access received Jira REST API issue JSON object properties and modify or add additional properties. will use only custom fields imported into the account. You can see the full Jira issue REST API in the browser. Please open JIRA_BASE_URL/rest/api/latest/issue/PPP-NNN?expand=changelog in your browser (where PPP-NNN is issue key) to see sample issue JSON. 

Save import options after the testing is done and JavaScript works as expected. will detect changes in import options and apply the JavaScritp code for any imported issue. 

Import Summary as an empty string

Here is an example of JavaScript code that will replace the issue summary property with an empty string for issues with issue type bug

if (issue.fields.issuetype && == "Bug") {
  issue.fields.summary = "";

Delete custom field values for bug issues

If you would like to delete some field values and do not import them in then use undefined.

if (issue.fields.issuetype && == "Bug") {
  issue.fields.customfield_NNNNN = undefined;

Use custom field ID instead of NNNNN in the example above.

Calculate resolution date creates a default set of measures based on the issue resolution date, for example, Issues resolved, Story Points resolved, etc. If the resolution date is missing in issues in Jira but you would like to have it in you can use custom JavaScript code to calculate one. The example below will calculate the missing resolution date for completed issues based on status.

// Resolution date
var resolvedStatuses = ["Done","Resolved","Closed","Complete","Fixed"]; // list all statuses representing resolved or closed issue
if (!issue.fields.resolutiondate && resolvedStatuses.indexOf( > -1) { // validations when there is no resolution date for issues in resolved status
  var resolutionDate = null;
  var stillOpen = true
      if (historyItem.field == "status") {
        statusFrom = historyItem.fromString;
        statusTo = historyItem.toString
        if (stillOpen && resolvedStatuses.indexOf(statusTo) > -1 && resolvedStatuses.indexOf(statusFrom) == -1) {
           stillOpen = false;
           resolutionDate = history.created;
        else if (!stillOpen && resolvedStatuses.indexOf(statusFrom) > -1 && resolvedStatuses.indexOf(statusTo) == -1) {
          stillOpen = true // reopened
          resolutionDate = null

// completed status at the issue creation
	if (resolutionDate === null && resolvedStatuses.indexOf( > -1 ) {
		resolutionDate = issue.fields.created;

  if (resolutionDate) {
  issue.fields.resolutiondate = resolutionDate;
// resolution date ends

Eliminate all user dimensions for GDPR compliance

You may disable data analytics from the user perspective who created or worked on the issues by eliminating data in dimensions Assignee, Reporter, Transition Author and Logged by. These dimensions will remain in the cube but all metrics will show up for the (unassigned) or (none) user.

issue.fields.assignee=null; //eliminate assignee
issue.fields.reporter=null; //elimenate reporter
for (i=0; i<issue.changelog.histories.length;i++) {
  hist = issue.changelog.histories[i];; //eliminate transition author
  for (j=0;j<hist.items.length;j++) {
    if (hist.items[j].field=="assignee") { //eliminate assignee history
//eliminate logged by
if (issue.fields.worklog) {
  if ( {;
