I am with AliGW on this... you are going to have to show several examples of the kind of text you are dealing with. One thing I am particularly interested in is if there can be more than one comma in the text.Hello I need the first letter after a comma to be lower case, any help is more than welcome
If you change your formula to this, it will not error out if the sentence does not contain a comma...=substitute(a1,mid(a1,find(",",a1)+2,1),lower(mid(a1,find(",",a1)+2,1)))
