I’ve gone through the entire list of Google Sheets and Excel formulas to identify the functions that SSDC doesn’t currently have. Here are the functions I’d like to see, with the functions in bold that are particularly important to me.
MAXIF, MAXIFS, MINIF, MINIFS
VALUE (and N, NUMBERVALUE)
FILTER, SORT, SORTBY, SORTN (relatively new array formulas)
IMAGE (google sheets, I really like how an image can expand and contract based on the cell size. Your Attachments data type is a great feature, but there are still uses for IMAGE)
SPARKLINE (google sheets - some very cool incell graphic potential)
SEQUENCE (google sheets - useful in array formulas)
[Array Formulas in general]
If I was doing more statistics, there are others that I’d like, such as QUARTILE, PERCENTRANK, VAR, COVAR, but I haven’t done a lot of that lately.
I’m extremely impressed with how many functions spreadsheet.com already has.
