Copying lots of data into a calculator and listing results back with original data

Your post does not comply with Rule 1 of our Forum RULES. Your post title should accurately and concisely describe your problem, not your anticipated solution.

Use terms appropriate to a Google search. Poor thread titles, like Please Help, Urgent, Need Help, Formula Problem, Code Problem, and Need Advice will be addressed according to the OP's experience in the forum: If you have less than 10 posts, expect (and respond to) a request to change your thread title. If you have 10 or more posts, expect your post to be locked, so you can start a new thread with an appropriate title.

To change a Title go to your first post, click EDIT then Go Advanced and change your title, if 2 days have passed ask a moderator to do it for you.

(This thread should receive no further responses until this moderation request is fulfilled, as per Forum Rule 7)

Just a note to all:

Since we a speaking here about PROTECTED calculator any solution with implifying breaking up security will end with closing thread and infraction to participants.

Only solutions that doesn't bypassing security will be allowed.

Thanks Zbor,
You are right. The only upside is I have 1 sheet that is unprotected which is the one with the list of postcodes on so we can play with that sheet.
