In OpenOffice Calc, one can change number format between standard United States, with decimal separator being a period .
, and the SI (International System) format with decimal separator being a comma ,
. This can be done by setting the language to US-English in the first case, and to Canada-French in the latter case (in the Format menu).
13.3 13,3
2.2 2,2
How can the same be done in Google Spreadsheets?
It does not seem that language can be changed within a same sheet (or maybe a same Google account ...?).
Is there another way?
Copy-paste from OO to Google does not work:
13/03/2014 13,3
02/02/2014 2,2
I dispute that comma as the decimal separator is " the SI (International System) format " - rather than one of ;-) - but think what you want is:
File > Spreadsheet settings ... and for Locale: choose somewhere like Canada (French).
Though beware, this could have ramifications beyond ,
