Don't split the number in smaller ones

[cronoser]

Hello;
First of all thank you for your tool, it's very easy to use and to fix the wrong numbers.
I have a little suggestion, in Spain the number are together. When people tell you a phone number in groups of two or three digits, it is for convenience, but that depends a lot on each user. The tool should not suggest splitting numbers into smaller numbers.
For example the correct phone is: +34947243154 without blank spaces.

Best regards

The grouping is done by libphonenumbers, which has data for each country on how phone numbers should be formatted.

The wiki suggests that spaces should be used between the country code and the local number and also within the number to separate the area code, but I know that there are personal preferences regarding that.

Looking at taginfo, it seems like in Spain there is also no consistency in whether or not to use spaces.

Personally, I don't really think it matters very much, and so there is never a suggestion to purely reformat a number. The fixes always involve something other than just adding or removing spaces. My preference when mapping is to include spaces, and that seems to be a common pattern with other mappers too, but not universal.

It would be possible to add a preference to the front end to not have any spaces in the resulting number, or to only have a space between the country code and the local number. I would accept a PR for this. Note that it would probably require moving diff-renderer.js to the client-side.
