How to check if cell is the last one in an Excel column -

-

this question has answer here:

i populating sheets database results. don't know how many rows result have. want have sheet variable number of rows has like:

if(this last row?, sum of previous cells, value)

is there formula determining row last one? looking excel formula not vba code. maybe similar lookup or index or offset not aware of.

you can try udf:

function islastcellinrow(mycell range) boolean     if isempty(mycell) exit function      if mycell.end(xldown).row = mycell.entirecolumn.rows.count         islastcellinrow = true     end if end function

the function checks if there non-empty cells below given cells , return true of false.

you can use udf this:

=if(islastcellinrow(sheet1!a1),sum(sheet1!a:a), "whatever")

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
