How do you set default font in calc v7.1? There are a number of instructions on the internet, but none work.
You need to modify the default templates of the applications - if you meant the default font of the Writer, Calc, and more…
Very often the expression “but none work” or something similar in relation to “font in Calc” is written when they mean importing CSV files. Are you asking about the font for this case?
Got it. 1st, open a blank document (calc, write). Make the desired font changes. Then - File - Templates - Save as Template. Name the template, and select “My Templates” in the “Template Category” dialog box. Check the “Set as default” box, save and exit. Now, how do I close this thread as “question answered?”
