要約

To import many values into a custom field, consider using a CSV file to bulk import values instead of having to manually enter them.

Import with a customized CSV file

Using the Importing data from CSV feature, you can create new issues. If you specify new values of custom fields during this import, this will create the field value in Jira. This means you will have to create a "dummy" issue for the purpose of importing the custom field values

Steps

1. Create a CSV file with all the values you want to add.
   1. You can refer to the following file for the formatting: importcustomfield.csv
      The file above is meant for an example Jira project with the project key of PROA. You can either create a new dummy project or rename the issue keys to an existing project from your Jira instance.
2. In Jira, navigate to the External System Import page and select CSV.
3. Select the CSV file you just created and click Next.
4. Select the project you want to import this issue to. The chosen project should have the same project key as that in the CSV file.
5. Map the 3 fields accordingly and check the boxes at the end of all 3 fields. Once all boxes are checked, click on Next.
6. Confirm the values which will be imported and click Begin Import.
7. Once that is done, verify that the custom field values are created for the Custom Field page.
8. (Optional) Delete the dummy issue once it is done to remove it from the system.

Import using a third-party add-on

Some 3rd party add-ons provides these features. For example, ScriptRunner for Jira has the Bulk Import Custom Field Values feature. Other add-ons may offer similar functionality.
