In a sheet where the range A2:A200 contain text strings and some are empty, the array formula {=SUM(Len(A2:A200))} adds one to the sum for every empty cell. {=SUM(IF(ISBLANK(A2:A200),0,LEN(A2:K200)))}, however, works correctly - but the if(isblank()) shouldn't be necessary. It seems to be more than just the SUM function, as I tried the QUARTILE function with LEN as an array function and I also got the result 1 when I was expecting 0. So perhaps any time you do an array function LEN() with empty cells, LEN gives 1 when it should give 0. (Needless to say the nonarray variation where you use a range of cells to perform the same calculation e.g. =LEN(A2) =LEN(A3) =LEN(A4) =LEN(A5) ... =LEN(A199) =LEN(A200) =SUM(B2:B200) works fine. See demonstration of the problem in cell B12 here: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1273659/+attachment/3962696/+files/Array%20Formula%20Bug.ods
