Slightly odd Count question

[phillippaige]

I have a large (100k rows) dataset with a set of about 10 columns. I need a formula to search those columns for a given value (which will then be something that gets repeated about 200 times for different values) and return the number of rows on which it finds that value in any of the 10 columns.

However the data is such that on some rows, the value may appear in only 1 column, whereas on others the value will appear 2-3 times on the same row in differing columns. I need it to only count rows where that multiple occurrence happens as 1 instance.

Any smart way of doing this other than a rather nasty (and slow) loop in VBA? All help much appreciated!

Can you add a column with a formula that just returns a 1 if the value is present in each row? Then all you need to do is sum that column.

Thanks Rory, I absolutely could, though given I'm looping 200 times against what would then be 100k formulae I'm thinking performance might be a bit iffy. Was hoping there was some kind of array style of count but which would check presence in a row.

I think you're looking for something along the line of:
{=SUM(--(MMULT(--(A1:F12="yes"),TRANSPOSE(COLUMN(A1:F12)))>0))}
where "yes" is the value you're looking for and of course set the range to your entire range.
NOTE: This is an array formula.

THAT is rather special! Thanks very much (to both of you) for your help!
