Created attachment 150573 [details] This file is originally a ms 2003 xml file, that it's extension is renamed to xls for automatic import to Libre I am producing xml files in ms excell 2003 xml format. There was no problem in importing this file up to LibreOffice 5.4.2.2 release, but with the releases of 6.*, not anymore. To experiment, I also exported one Libre spreadsheet to ms 2003 xml, then import to Libre back, but not working. Thanks.
