Thanks very much for making the order of the output the same as the input! Please also retain blank lines in the output, again for copying back into a spreadsheet. Copying back would be even easier if the output could be formatted as an HTML table instead of as text with a colon separator.

It should now cope with blank lines.

Great tool, but it halts without warning if the data contains a blank line.

On 16th August 2017, point noted. We have this on our list of things to investigate. Watch this space...

Batch conversion is excellent, thanks! It would be *even better* if it could retain the ordering of the input postcodes, for copying back into a spreadsheet.

My place has had 3 postcodes allocated. This converter worked for all three no problem. Now to see the grid references to see why it keeps moving!

Zyda, this just has more precision. So instead of AB 12345 67890 you could use AB 123 678 and loose some of the precision.

Hello - I was expecting 2 letters and 6 digits. but instead I get 2 letters and 10 digits...? Can you help?

Hi, can you explain why it doesn't work? Does it return an NGR code? If so, do you think it is wrong?
