Column E on my spreadsheet contains a series of values TRUE and FALSE in no

won't bore anybody with.) I need a formula in column F that checks if the
corresponding cell in column E contains "TRUE" and if so, it counts the
number of "TRUE's" below it before the next occurrence "FALSE."

You can do it easily with two columns. For example if the first element
is at E2:

[F2] = IF(E2,F3+1,0)
[G2] = IF(F1,0,F2)

And then copy these formulas down the length of your column.

This expects your E1 column to be initialized FALSE or 0. You can then
set the F column to some tiny font and close up the column width so it
isn't distracting.

To do it with a single column may require a bit of VBA to create a
custom function. Perhaps someone else here will have a better suggestion.
