I thought I had mentioned this somewhere, but I can’t find it. This is a general request/need for support for custom number formats, compatible with the same custom number formats (or as the same as possible) as Excel and Google Sheets.
In case this won’t be a possibility, I’ll use this post to list the number formats that I need for compatibility with other spreadsheets.
DATE FORMATS:
“d” for displaying just the day of the month “1, 2, 3, 4 …”
“mmm” for displaying the abbreviated month name like “Jan, Feb, …”
“mmmm” for displaying the full month name like “January, February, …”
“mmmm yyyy” for displaying a common month label like “January 2020”
“mmm yyyy” for displaying an abbreviated month and year like “Jan 2020”
“mmm 'yy” for displaying an abbreviated month and year like “Jan '20”
“ddd m/d/yy” for abbreviated dates in project schedules where you want to know the day of the week like “Mon 9/21/2020”
“ddd d/m/yy” for the UK format
TIME FORMATS:
“h:mm AM/PM” for displaying just the time instead of the date and time like “4:30 PM”
“[h]:mm” for displaying duration in hours and minutes like “52:23”
