The ideal way to export tickets is to set the time range under the 'Filter Tickets By' section in the 'Export Tickets' section. First, choose the preferred file format, set the desired range select the required fields to export and click 'Export'. Ensure that the FILTERS section in the Tickets list view does not have any date range specified (or) set as Any time. If any date range is set there, the export will only include tickets from that specified range.
