Bulk Create Azure Active Directory User

Sign in to your Azure AD organization with an account that is a User administrator in the organization.
In Azure AD, select Users > Bulk create.
On the Bulk create user page, select Download to receive a valid comma-separated values (CSV) file of user properties, and then add users you want to create.
Open the CSV file and add a line for each user you want to create. The only required values are Name, User principal name, Initial password and Block sign in (Yes/No). Then save the file.
On the Bulk create user page, under Upload your CSV file, browse to the file. When you select the file and click Submit, validation of the CSV file starts.
After the file contents are validated, you’ll see File uploaded successfully. If there are errors, you must fix them before you can submit the job.
When your file passes validation, select Submit to start the Azure bulk operation that imports the new users.
When the import operation completes, you’ll see a notification of the bulk operation job status.
You can see the status of all of your pending bulk requests in the Bulk operation results page.
