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.

Having Convert NGR to Postcode in the app would be great feature. I volunteer as an emergency rescuer and often I have find places on a map quickly to attend a location

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

Brilliant tool. Will there be an app?

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?
