• In your table, try creating a group (outside of any current grouping you have) with no header or footer, and the page break after value set to true. For the grouping value, use an expression similar to

    =ROWNUMBER(Nothing) MOD 60000

    This should force a page break after 60000 rows of data, which will translate into a new excel tab when you export. I believe the 65K limit in Excel is on a per worksheet basis.
