It may happen that employees are absent and that when you export the “Absenteeism” report, their absences are not present in the exported report.
First of all, you need to know that for an absence to appear in this report, you need to have left the time entry blank with the words "Missing time entry."
If you don't see certain absences in your report, check your employees' timesheets. It's highly likely that "Absence" has be chosen as a time off type has been, rather than leaving the time entry blank.
If this is the case, don't panic! You can use another report to account for absences entered as “Absence."
Simply export the "Time entries" report on the "Reports" tab -> "Attendance" category.
Be sure to select the date range of your choice, then under "Options" choose "Only show time offs" then select the type of time off (Sick leave, Absence, etc.)
