In Realtime, go to Dashboard >> Tasks: Export Time Cards: Execute.
In the Timecard Export window, select the pay period(s) you want to export:
You can change the date range selection if needed, but most likely you will be exporting the Previous Pay Period, which is the default selection.
You can select an Export Type, if you have more than one Export Definition set up, and want to use one that is not the default assigned to the pay period rule(s). Otherwise, leave "[Preset]" selected for Export Type, and the default export definition will be used.
Click Execute.
A "Save as" button will appear under the Pay Period(s) you selected. Click on it, and save the export file down to your computer. The exact prompt will depend on your browser and its settings.
Finally, open your payroll software and import the export file from the save location.
