OK, the big picture is to use all my API Steam results inside Google Spreadsheet so I can create a database of my games and profile.
note: I don't want to share my private STEAMID for security reasons
So far so good, using the command =importXML(url, xpath_query, locale). I tried.
=IMPORTXML("https://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=XXXXXXXXXXXXXXXXXXXX&steamids=XXXXXXXXXXX&format=xml", "/html/body/div[3]/div/div[2]/div/div[2]/div/div[2]/div[4]/span[2])"in the end I also tried changing , en_US) and removing the,
notice that my xml locale appears ES because it is in Spain.
But I believe that's not the reason for the error rather escaping the characters /?: and any other if I didn't find it.
I tried to escape ? with ~ but the failure persists.
Why am I using xpath? is because it's the only way I know for now. I'll try python later or I could just import the .json inside the Spreadsheet but for now I need xpath.
the url above with STEAMID provides me a resulting file in .json, .xml, or .vdf
