excel - OpenOffice saves empty cells in xlsx -

-

i'm processing xlsx files in php. when create xlsx file using openoffice 1 filled cell, spreadsheet has 65536 rows itself. looks openoffice stores cells if empty. there solution can save many rows/columns filled? because every library parsing xlsx produces wrong number of rows i'm not able process correctly. solution achieve directly inside openoffice, or use external tool/script (*nix based) clean such xlsx file if possible.

here 1 solution:

use opentbs open xlsx , save or without modifications.

opentbs pure php tools purpose merge data libreoffice , ms office documents using technique of templates.

since version 1.9.0, opentbs can handle xlsx workbooks made libreoffice. such xlsx workbooks may have row definition contains repetition attribute extends upon maximum limit of row number. opentbs reduce extended row single row.
