When exporting to Excel, the worklog time is shown in minutes. Minutes seems to be the Jira internal logging unit.
For all other purposes, minutes will be almost useless. Teams and management will want to see time in hours.
Worklog does convert nicely in the online views.
Would be nice if you could add a column in Excel that shows time in hours. This would save the effort to take each Excel for each person and add a calculated column. I found that this takes up a lot of time.
