over 9 months ago in post #6 it was suggested posting a sample workbook so we would all be dealing with the same thing.
You're now suffering the consequences of not doing so. When you don't help people willing to help you, they inevitably ignore you.

All through this thread you've said rows that don't contain
... there's 16,384 cells in a row, so you'd need to check them all. Right ?

Apparently NOT. What you've now deleted indicates rows that don't contain is misleading.

Now you've asked to have this thread deleted.

If you read this before the deletion and are inclined to create your own macro...
. determine the last row of column A
. step -1 from last row to first row
. use Instr to check for words in the A column cell of the row
. if Instr gives 0 for each word then Acolumncell.entirerow.delete
