The reason i want to do conversions via commandline is because any other option made in php/laravel is to slow and/or uses to much memory. I read through the libreoffice filter parameters and option 5 seems to be what im looking for, yet its not working, and in practise i dont know which colomns are date fields before hand, the conversion is done automaticly. i want my csv file to contain the original value, which is 12-11-1997. if i go into the on my windows machine and i save file as csv, it works correct. Issue is: xls/xlsx file contains dates as d-m-Y (12-11-1997), but when i use libreoffice or gnumeric via the terminal to convert to csv, it changes the dates to d/m/Y (), and in some cases Y/m/d (2).
