Regex again

Third party integrations Node-RED

Of all the forums I am a member of to get help, this one is the most responsive and helpful so here we are again.
I have previously asked for help with Regex and I still battle to get my head around it. I need to change all capitals to lower case and remove all spaces in a string

EG: Upper Laclan Shire

I need to make it
upperlaclanshire

Is that something i can do with Regex? I would previously read the string one letter at a time in a loop and work on each individual character and add it to a new string

You can use replace and lowercase in a jsonata field.

$lowercase($replace(payload, " ", "" ))
