I have Libre Office spreadsheet program. I had to send a friend a spreadsheet.
I sent .ods file and she could not en it. I renamed it .xls and I could use
that format but when I sent it to her, as an attachment, it had the word lock as
part of the name although I did not save it with lock. Anyway she could only
read a couple of lines. How can I send the file so she can open it?
