Hi,
Im trying to import the following weather data from an .JSON API. I have tried "webread" on the URL but I dont know how to extract the wheather data values as shown in the table in the bottom of this post.
URL:
https://bank.stat.gl:443/api/v1/da/Greenland/EN/EN30/ENX1SUM.px
JSON query:
{
"query": [
{
"code": "weather station",
"selection": {
"filter": "item",
"values": [
"5"
]
}
},
{
"code": "time",
"selection": {
"filter": "item",
"values": [
"0",
"1",
"10",
"11",
"12",
"13",
"14",
"15",
"16",
"17",
"18",
"19",
"2",
"20",
"21",
"22",
"23",
"24",
"25",
"26",
"3",
"4",
"5",
"6",
"7",
"8",
"9"
]
}
}
],
"response": {
"format": "px"
}
}
and I expect the follow table to be imported as shown in the table which was generated on this homepage: https://bank.stat.gl/pxweb/da/Greenland/Greenland__EN__EN30/ENX1SUM.px/table/tableViewLayout1/

Your URL doesn't seem to contain the data, but only the row/col headers:
data=webread('https://bank.stat.gl:443/api/v1/da/Greenland/EN/EN30/ENX1SUM.px')
data = struct with fields:
title: 'Summerede graddageværdier efter vejrstation og tid' variables: {2×1 cell}
data.variables{1}.valueTexts
ans = 20×1 cell array
{'Nanortalik' } {'Qaqortoq' } {'Narsarsuaq' } {'Narsaq' } {'Paamiut' } {'Nuuk' } {'Kapisillit' } {'Maniitsoq' } {'Kangerlussuaq' } {'Sisimiut' } {'Qasigiannguit' } {'Kangaatsiaq' } {'Aasiaat' } {'Ilulissat' } {'Qeqertarsuaq' } {'Uummannaq' } {'Upernavik' } {'Qaanaaq' } {'Tasiilaq' } {'Ittoqqortoormiit'}
data.variables{2}.valueTexts
ans = 27×1 cell array
{'1995'} {'1996'} {'1997'} {'1998'} {'1999'} {'2000'} {'2001'} {'2002'} {'2003'} {'2004'} {'2005'} {'2006'} {'2007'} {'2008'} {'2009'} {'2010'} {'2011'} {'2012'} {'2013'} {'2014'} {'2015'} {'2016'} {'2017'} {'2018'} {'2019'} {'2020'} {'2021'}
