I have a spreadsheet with a lot of rows 50K, I need to do an action if
column the value in "N" is one of 8 to 14 numbers. Such as

If N.value = 1,2,3,4,5,6,7,14,121,122,123,124,201,202
then do something
else do nothing

There will be 10 of these statements, so maybe a case statement like

case 1,2,3,4,5,6,7,14,121,122,123,124,201,202
do something
case 151,152,153,154,155,156,157,214,215,216
do something


any suggestions?
