Thanks for the feedback Bill. This has been implemented.

One thought though that would improve the user experience - how about a message informing the user that the conversion process was underway? I was a bit worried the first time that nothing was happening after I hit the convert button.

Amazing! What a brilliant solution to my very niche problem (plotting the location of WWII Pillboxes in Google Maps). Well, I did say it was niche! Happy to make a donation.

What is the maximum number you can batch convert and can it be export as an excel file?

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.

Is there a possibility to do 10 different coordinates at once?

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?
