https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23685 --- Comment #9 from David Cook <dcook@prosentient.com.au> --- An alternative solution might be to write a CSV file to a temporary file and then use LibreOffice's CLI tools to convert from CSV to ODS. Example: soffice --convert-to ods koha.csv --headless I haven't tried that though, so I can't speak to its performance. I seem to recall Indranil saying OpenOffice or LibreOffice had some memory usage issues for large spreadsheets. It might not be any better. Plus, it would add a large dependency to Koha for just 1 thing. I think that's all I have for ideas though. I think the ODS format is just problematic - at least with the tools that we have to hand. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
