The data export tool will be accessible on the cloud and from the version 1.14.0 of Elements Checklist on-premise.
Following the announcement of the archival of Elements Checklist, we want to provide a way to retrieve all your data. The data export tool is available for each project and can be used even without an active license. You can easily access the tool by clicking on the Elements Checklist settings under the Project setting of your current project. To retrieve all data of your instance, you will need to repeat this export for each Jira project for which you want to retrieve Checklist data.
To export all data related to the project in question, click on the "Export Checklist data" button. Once the export is completed, a button "Download the export" will appear so that you can retrieve a JSON file. The JSON file exported is defined here.
