Great but... can't you have it displayed in a table so we can just copy the list of post codes? Thank you.

for me it duplicates quite a few of my grid references e.g. I submit a list of 10 and it returns 15, with some duplicates

Graham, you can list multiple in the text box by using one per line.

You do need to include the first 2 letters. It can then be a 4, 6, 8 or 10 digit reference number (separated with a space)

do you have to include Map letters e.g SU? do you write 3,4 or 5 figure grid reference?
